&amp;nbsp; &amp;nbsp; &lt;span style="font-family: Times, Times New Roman, serif; font-size: large;"&gt;Os logaritmos foram inventados para simplificação de contas. Depois surgiram outras finalidades.&amp;nbsp;Atualmente perderam a função de simplificar contas por causa de máquinas de calcular, mas restaram as outras funções.&lt;/span&gt;&lt;/div&gt;
&lt;span style="font-family: Times, Times New Roman, serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Times, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; &amp;nbsp;Você deve se lembrar que:&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: Verdana, sans-serif; font-size: large;"&gt;&lt;b&gt;*População&lt;/b&gt;: é qualquer conjunto de elementos que tenham, entre si, pelo menos uma característica comum&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: Verdana, sans-serif; font-size: large;"&gt;Valores obtidos em uma &lt;b&gt;população&lt;/b&gt; são chamados de parâmetros.&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style="font-family: Verdana, sans-serif; font-size: large;"&gt;Valores obtidos em &lt;b&gt;amostras&lt;/b&gt; são chamados de estatística.&lt;/span&gt;&lt;/div&gt;

&lt;span style="color: #990000; font-family: Trebuchet MS, sans-serif; font-size: x-large;"&gt;RESPOSTA:&amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;A N-haloamina&amp;nbsp; é Heterogênea, pois possui um heteroátomo entre Carbonos .&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;E esse Heteroátomo é o Nitrogênio .&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;2) É Saturada , pois os carbonos só possui ligações simples entre eles.&amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: large;"&gt;3) E por último é Ramificada , observe que possuis radicais metil ( CH3)&amp;nbsp; nas pontas .&lt;/span&gt;&lt;br /&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;A raiz quadrada (√) de um número é determinada por um&amp;nbsp;&lt;span style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"&gt;número real positivo elevado ao quadrado&lt;/span&gt;&amp;nbsp;(x&lt;span style="box-sizing: border-box; line-height: 0; position: relative; top: -0.5em; vertical-align: baseline;"&gt;2&lt;/span&gt;). Já na raiz cúbica, o número é elevado ao cubo (y&lt;span style="box-sizing: border-box; line-height: 0; position: relative; top: -0.5em; vertical-align: baseline;"&gt;3&lt;/span&gt;). Além disso, se a raiz for elevada a quarta potência (z&lt;span style="box-sizing: border-box; line-height: 0; position: relative; top: -0.5em; vertical-align: baseline;"&gt;4&lt;/span&gt;) é chamada de raiz quarta, e se for elevada a quinta potência (t&lt;span style="box-sizing: border-box; line-height: 0; position: relative; top: -0.5em; vertical-align: baseline;"&gt;5&lt;/span&gt;) é raiz quinta.&lt;/span&gt;&lt;/div&gt;

Como calcular a raiz quadrada?&lt;/h2&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;&lt;span style="text-align: start;"&gt;Para saber a raiz quadrada de um número, podemos pensar que um número elevado ao quadrado será o resultado. Portanto, o conhecimento da&amp;nbsp;&lt;/span&gt;tabuada&amp;nbsp;&lt;span style="text-align: start;"&gt;e de&amp;nbsp;&lt;/span&gt;potenciação&lt;span style="text-align: start;"&gt;&amp;nbsp;são extremamente necessários.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;No entanto, alguns números são difíceis por serem muito grandes. Nesse caso, utiliza-se o processo de&amp;nbsp;fatoração, por meio da decomposição em&amp;nbsp;números primos.&lt;/span&gt;&lt;/div&gt;
&lt;div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; text-align: justify; vertical-align: baseline;"&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Note que a potenciação é necessária, uma vez que depois de fatorar o número, no caso da raiz quadrada, reunimos os números primos em potências de 2.

Quem faz esse tipo de alerta conhece muito bem a importância do consumo consciente. Desde&amp;nbsp; a Antiguidade até os nossos tempos, a humanidade aumentou milhares de vezes o gasto de energia para suas atividades diárias. Um habitante da Grécia antiga, por exemplo, tinha um consumo energético muitas vezes menor do que um sul-americano médio de hoje. As diferenças ocorrem também entre as diversas regiões de um mesmo país e ainda entre as classes sociais em cada região. Um indígena do Alto Xingu consome bem menos energia que os habitantes do centros urbanos brasileiros, que dela dependem para se locomover, aquecer e iluminar suas casas e acionar eletrodomésticos, por exemplo.&lt;/span&gt;&lt;/div&gt;

Em jornais e revistas, noticias sobre o uso de fontes energética costumam aparecer mais nos cadernos econômicos que nos de Ciência. Contudo, as questões políticas e econômicas que envolvem a tomada de decisão da produção e uso de energia dependem de pareceres de engenheiros e cientistas. São os conhecimentos desses profissionais que orientam políticos sobre os recursos energéticos disponíveis e a melhor forma de distribuí-los, a fim de suprir a necessidade da nação de modo sustentável.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;Para compreender o aumento do consumo energético, vamos retroceder ao fim do século XVII, na Inglaterra. Até essa época, boa parte da energia consumida provinha da tração animal, usada tanto para o transporte de pessoas como para o funcionamento de máquinas. Havia também energia hídrica, originada da água de rios ou pequenos córregos para movimentar monjolos e moinhos,e eólica, ou seja, do vento, para mover embarcações e moinhos de vento. O calor, outra forma de energia, era obtido da queima de madeira e carvão para aquecer o ambiente e os alimentos.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;A escassez&amp;nbsp; de madeira fez com que a procura por outros recursos aumentasse. Assim, o carvão se tornou a principal fonte de energia e não mostrou ser um grande problema quando as minas desse mineral se encontravam próximas da superfície. Na extração de materiais do subsolo, o minério de ferro, matéria-prima da metalurgia, ganhou importância. com o tempo, porém, esses recursos se tornaram raros, obrigando os mineradores a procurá-los em profundidades cada vez maiores. Isso levou ao surgimento de um novo problema: a água. As escavações mais profundas podiam atingir os lençóis freáticos, que alegavam as minas.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

Esse dispositivo, criado pelo matemático grego Arquimedes (c. 287 a.C. -c. 212 a.C), consistia em bombear água do fundo da mina para a superfície por meio de um parafuso que girava no interior de um cilindro oco. Esse mecanismo foi usado com muita frequência, mas, como a rotação do parafuso era obtida por tração humana ou animal, buscou-se obter um processo automático e mais eficiente.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;A explicação sobre essa limitação foi dada por um discípulo de ]galileu Galilei (1564 - 1642), o italiano Evangelista&amp;nbsp;Torricelli (1608 - 1647), que relacionou a elevação de um liquido em um tubo com pressão exterior (atmosférica). Foi somente com o desenvolvimento dos estudos sobre as transformações nos gases e das máquinas que térmicas que se tornou possível construir bombas capazes de retirar a água de profundidades maiores.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;Em 1680, o físico e matemático holandês Christiaan Huygens (1629 - 1695) construiu uma bomba de vácuo movida á explosão de pólvora. Mas foi seu assistente, o físico francês Denis Papin (1647 - 1712), quem primeiro montou um eficiente sistema que transformava o vapor em movimento. Bem antes dele, na Grécia Antiga, Heron (65 - 125) construiu um aparelho capaz de girar pela ação do vapor, mas que não passou de mera curiosidade. Papin desenvolveu também um digestor, um tipo de panela dotado de uma válvula na tampa que permitia controlar a pressão interna no recipiente. O dispositivo foi o percursos das panelas de pressão.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;Essa válvula consistia em uma haste com um peso na extremidade, que funcionava como uma alavanca interpotente sobre a tampa da panela. Quando a pressão no interior da panela atingia determinado valor, a válvula se abria, permitindo o escape parcial do vapor. O desenvolvimento desse dispositivo tornou as máquinas térmicas bem mais seguras para os operadores.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

Variando a massa do peso, pode-se controlar a pressão interna.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: small;"&gt;&lt;span style="font-size: large;"&gt;A primeira máquina a vapor de grande porte que teve sucesso comercial foi inventada pelo engenheiro militaar inglês Thomas Savery (1650 - 1715). O princípio de funcionamento dessa máquina é, de maneira simples, análogo ao que aplicamos quando tomamos suco com auxílio de um canudinho. Quando sugamos o ar para dentro da cavidade bucal, reduzimos a pressão no interior do canudo. Como o líquido está sob pressão no interior do canudo, ele sobe até a boca.&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;&lt;span style="color: #990000; font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: small;"&gt;&lt;span style="font-size: large;"&gt;A figura mostra a máquina criada por Savery e como ela funcionava. Ela era constituída de uma caldeira integrada a um cilindro e a uma série de tubos e válvulas. A ideia era simples: deixando somente as válvulas &lt;i&gt;A&lt;/i&gt;&amp;nbsp;e&lt;i&gt;&amp;nbsp;B&lt;/i&gt;&amp;nbsp;abertas, o vapor produzido pela caldeira começava a empurrar o ar e a água do cilindro para o meio externo.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: small;"&gt;&lt;span style="font-size: large;"&gt;Quando o sistema estava bem quente fechava-se a válvula &lt;i&gt;B &lt;/i&gt;e abria-se a válvula &lt;i&gt;C. &lt;/i&gt;Resfriando-se o cilindro, a pressão diminuía e a água da mina era empurrada para esse recipiente pela pressão atmosférica. A abertura da válvula &lt;i&gt;D&lt;/i&gt;&amp;nbsp;permitia que parte da água do tubo fosse desviada para resfriar o cilindro. Mesmo possuindo uma válvula de segurança, a utilização de vapor e alta pressão acabou provocando muitos acidentes.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;que algumas importantes inovações fossem introduzidas nesse sistema. A base dessa máquina era a mesma da máquina de Savery, ou seja, havia uma caldeira que ao ser aquecida produzia vapor, mas acrescentou-se um sistema de cilindro e pistão.&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-size: large;"&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;Na montagem anterior, ao empurrar o pistão para cima, o vapor provoca a elevação de um dos braços da balança e a consequente descida do outro. O resfriamento do cilindro causa a descida do pistão devido à diferença de pressão gerada. Nas minas, o vaivém repetidos dos braços levava a água para a superfície. Esse método mostrou-se muito útil também no levantamento de cargas. Um jovem aprendiz que trabalhava em uma dessas máquinas, Humphrey Potter, criou um dispositivo capaz de realizar automaticamente a tarefa de elevar cargas, aproveitando o próprio movimento do sistema. As principais desvantagens da máquina de Newcomen eram o longo tempo necessário&amp;nbsp;para o resfriamento do cilindro&amp;nbsp;e o grande consumo de carvão para o seu funcionamento.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

Para um melhor aproveitamento da energia, Watt desenvolveu uma máquina dotada de um sistema duplo de cilindro e pistão. Assim, quando um dos cilindros fosse aquecido, o pistão correspondente seria empurrado para cima e um sistema de engrenagens se encarregaria de abaixar o outro braço e o pistão que movimentaria uma roda acoplada a eles. Em vez de resfriar o cilindro, o vapor quente seria conduzido ao outro cilindro, onde ocorreria&amp;nbsp; a sua condensação.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: x-large;"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif;"&gt;&lt;span style="font-size: large;"&gt;Essa modificação possibilitou uma série de inovações nas máquinas que resultaram em um ganho de rendimento de praticamente 50% sobre a máquina de Newcomen e uma economia de carvão de quase 70%. Alem da separação entre fonte quente e fonte fria, o engenheiro escocês desenvolveu também uma válvula constituída de duas esferas que ao girarem provocam a abertura da válvula de escape final da máquina, que permitia controlar a velocidade do sistema. Esse invento teve a sua patente registrada em 1769, transformando Watt em um homem rico.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

O desenvolvimento das máquinas térmicas provocou uma redução do número de trabalhadores necessário para o trabalho, gerando um aumento gradativo do desemprego, principalmente a partir do século XVIII. Apesar da massa de desempregados, o crescimento da produção teve como efeito o barateamento dos preços dos produtos e um consequente aumento do consumo. A aplicação dessas máquinas para para movimentar trens, navios e mesmo automóveis foi responsável&amp;nbsp;por uma transformação&amp;nbsp;crucial&amp;nbsp; nos transportes, oferecendo maior mobilidade às pessoas.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp;&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: medium;"&gt; Ilustra-se a seguir, como exemplo, a exposição teórica da primeira lei da eletrólise, procurando-se enfatizar mais os conceitos e princípios, conhecimentos anteriores e raciocínio e princípios, conhecimentos anteriores e raciocínio em vez da apresentação direta da fórmula, que nada exige do aluno nesses aspectos.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Supondo-se que a eletrólise qualitativa já tenha sido ensinada, pode-se iniciar a discussão perguntando como calcular a massa de substâncias depositadas em eletrodos.&lt;/span&gt;&lt;/div&gt;
&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Lançado o problema, recorre-se a um caso particular, como a eletrólise do AgNO&lt;span style="font-size: xx-small;"&gt;3&lt;/span&gt;, por se tratar de íons monovalentes, o que facilita a discussão. Analisa-se primeiramente o que ocorre no cátodo, por ser a prata uma substância sólida nas condições ambientais e ser mais conhecida do aluno.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; É mostrado, então, como esse metal será depositado:&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;/div&gt;
&lt;div style="text-align: center;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif;"&gt;&lt;span style="font-size: large;"&gt;(Ag+)&amp;nbsp;+ (e -) = (Ag&lt;/span&gt;0&lt;span style="font-size: large;"&gt;)&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: center;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif;"&gt;&lt;span style="font-size: large;"&gt;2(Ag+)&amp;nbsp;+ 2(e -) = 2(Ag&lt;/span&gt;0&lt;span style="font-size: large;"&gt;)&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: center;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif;"&gt;&lt;span style="font-size: large;"&gt;3(Ag+)&amp;nbsp;+ 3(e -) = 3(Ag&lt;/span&gt;0&lt;span style="font-size: large;"&gt;)&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: center;"&gt;

&lt;div style="text-align: center;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif; font-size: large;"&gt;.&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;.&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: center;"&gt;
&lt;span style="font-family: &amp;quot;trebuchet ms&amp;quot; , sans-serif; font-size: large;"&gt;.&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;.&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: center;"&gt;
&lt;/div&gt;
&lt;br /&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;br /&gt;
&lt;div style="text-align: left;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Por indução, o aluno concluirá que, quanto maior o número de átomos depositado, maior será a massa correspondente. Mas, para que isso ocorra, é necessária uma quantidade maior de elétrons, implicando maior carga elétrica. É proposta, então, a seguinte pergunta: essas grandezas podem ser relacionadas?&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="text-align: left;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Sugere-se que poderia haver uma relação entre a massa de prata e os elétrons fornecidos durante a eletrólise. O desenvolvimento a seguir poderá ajudar a encontrar a resposta.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="text-align: left;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Para neutralizar um único íon (Ag+), é necessário um elétron, cuja carga é 1,6 x 10^-19C. Assim, forma-se um átomo de prata cuja massa é 107/6,02 . 10^23g. ou seja, 2 . 1,6 . 10^-19C. Agora são produzidos dois átomos de prata, cuja massa total é 2 . (107/6,02 . 10^23)g. O mesmo procedimento se repete para 3 íons, e assim por diante, conforme mostrado na tabela abaixo:&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div class="separator" style="clear: both; text-align: justify;"&gt;

&lt;div class="separator" style="clear: both; text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; &lt;span style="font-family: Georgia, Times New Roman, serif; font-size: medium;"&gt;A partir dessa tabela pode-se encontrar a fórmula m = K . Q, correspondente á primeira lei da eletrólise, propondo-se a seguinte pergunta: analise as colunas "carga correspondente dos elétrons" e "massa do átomos produzidos", respectivamente, e responda: Qual será a massa m de prata produzida quando passar na célula eletrolítica uma quantidade de carga elétrica Q?&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class="separator" style="clear: both; text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; A resposta se´ra facilmente encontrada relacionando-se quaisquer valores da carga dos elétrons e da massa dos átomos com a carga Q e a massa m, respectivamente. Uma vez que a proporcionalidade entre essas grandezas é reconhecida, estabelece-se a proporção correspondente:&lt;/span&gt;&lt;/div&gt;

&lt;div class="separator" style="clear: both; text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Relembra-se ao aluno que 107 é o valor da massa molar atômica da prata. Assim, massas molares ou atômicas de outros elementos poderiam ser substituídas na expressão obtida. Portanto, generalizando-se para uma subtância qualquer, ter-se-á:&lt;/span&gt;&lt;/div&gt;
&lt;div class="separator" style="clear: both; text-align: left;"&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div class="separator" style="clear: both; text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Desse modo, propicia-se aos alunos uma participação efetiva na construção da fórmula obtida, em vez da sua imediata imposição, como normalmente ocorre.&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt; A utilização excessiva de fórmulas matemáticas em Química é bastante generalizada no ensino médio, sem que a fundamentação conceitual correspondente seja efetivamente assimilada pelo aluno, uma vez que a necessidade imposta de manipular expressões algébricas sobrepuja a da aquisição dos respectivos conceitos e princípios.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&lt;div style="text-align: justify;"&gt;
&amp;nbsp; A "mecanização mental" é nociva á formação do aluno, dificultando seu raciocínio e sua autonomia como cidadão. Essa prática promove poucas oportunidades para que o aluno, através de seus próprios conhecimentos e raciocínio, deduza, sozinho ou com uma orientação adequada, a maioria das fórmulas. É o caso, por exemplo, das fórmulas envolvendo as leis físicas dos gases, propriedades coligativas, eletrólise, etc. Desse modo, a maioria dos alunos não percebe os conceitos subjacentes, que acabam ficando ocultos pela excessiva manipulação algébrica.&lt;/div&gt;
&lt;/span&gt;&lt;br /&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp;&lt;b&gt; Essa forma de apresentar o conteúdo pode ser uma das causas que fazem com que, comumente, alunos do ensino médio sejam incapazes de resolver problemas, mesmo os mais simples, caso não disponham de fórmulas.&lt;/b&gt; Essa dependência é manifestada em algumas observações feitas por alunos quando deparam com problemas de Química.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&lt;span style="font-family: Trebuchet MS, sans-serif; font-size: medium;"&gt;&lt;br /&gt;&lt;/span&gt;
&lt;/span&gt;&lt;/div&gt;
&lt;ul&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Quais dessas fórmulas devo usar para resolver o problema?&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Sei qual é a fórmula para se aplicar, mas não consigo resolver o problema.&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Só consigo resolver um problema quando já resolvi outro parecido.&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Esqueci a fórmula e não consigo resolver esse problema.&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Apliquei uma fórmula no lugar da outra.&lt;/span&gt;&lt;/li&gt;
&lt;li style="text-align: justify;"&gt;&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;Tem muita fórmula para decorar.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Para reverter esse quadro, é preciso adotar outras estratégias de ensino que priorizem a compreensão do fenômeno, a apropriação dos conceitos estudados. Sendo assim, qualquer generalização deve ser deduzida e analisada a partir do relacionamento e significados envolvidos, antes de ser transmitida ao aluno. Esse objetivo deveria estar presente em todo ensino e, particularmente, nos conteúdos que exigem o manuseio de fórmulas. com&amp;nbsp; a sistemática geralmente empregada, entretanto, ele dificilmente é atingido. Assim, as fórmulas matemáticas devem ser ensinadas através dos conceitos que expressam e reconstruídas a partir destes, em vez de transmitidas diretamente.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; Uma possível alternativa para atingir esse objetivo é mostrar que os problemas podem ser resolvidos não somente pela aplicação das fórmulas, mas, também, na ausência destas. Desse modo, permite-se que os alunos tomem consciência de que não é necessário decorar tais fórmulas. Isso, portanto, elimina, ou pelo menos ameniza, a ideia muito comum entre alunos do ensino médio de que a Química é "decoréba".&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; A aprendizagem de fórmulas, tal como aqui considerada, deve ser consequência e não antecedente dos conceitos e princípios. Somente quando estes fatos forem compreendidos e manipulados, as fórmulas poderão ser aplicadas como recursos sistematizadores, deixando então de ser, para grande parte dos alunos, um processo meramente mecânico.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; A relação entre conceito e fórmula deve ser entendida como tendo um caráter reversível. Se o estudante é capaz de resolver problemas através de formulas, deverá também poder resolvê-los por meio dos conceitos por elas expressos e das relações entre eles. Se essa reversibilidade não for desenvolvida por ocasião da aprendizagem inicial, a aquisição de conceitos e de suas respectivas fórmulas dar-se-á isoladamente. Daí, então, ser frequente encontrar alunos perguntando sobre o significado conceitual de uma fórmula.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: Georgia, Times New Roman, serif; font-size: large;"&gt;&amp;nbsp; A ausência da reversibilidade já mencionada pode provocar algumas consequências indesejáveis, como: a capacidade de o aluno racionar conceitualmente torna-se deficitária, o que o leva a desenvolver um hábito excessivo e desnecessário de memorização em detrimento de sua capacidade criadora, que o poderia conduzir, por si só, á fórmula desejada. Desse modo, nega-se ao aluno a possibilidade da descoberta e as consequências benéficas que disso resultam. Por outro lado, o professor, apesar de seus esforços, observará, perplexo, que seus alunos, quando solicitados a responder a questões conceituais, mesmo as mais simples, sentem enorme dificuldade. Tal fato acontece desde o início da aprendizagem, quando não é dada ao aluno a oportunidade de desenvolver o conteúdo de forma conceitual e não apenas algébrica, tanto na exposição teórica como nos problemas.&lt;/span&gt;&lt;/div&gt;

Um triângulo possui três medianas. Através da Geometria analítica podemos determinar as medidas das medianas de um triângulo. Vejamos:&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align: justify;"&gt;

&amp;nbsp; &lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Vamos determinas a medida da mediana relativa ao lado &lt;b&gt;BC&lt;/b&gt;:&lt;/span&gt;&lt;/div&gt;
&lt;div class="separator" style="clear: both; text-align: left;"&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;&amp;nbsp; Por meio de um procedimento análogo, podemos determinar o comprimento das medianas &lt;b&gt;BN&lt;/b&gt;&amp;nbsp;e &lt;b&gt;CP&lt;/b&gt;.&lt;/span&gt;&lt;/div&gt;

Veja, por exemplo, a mediana &lt;b&gt;CN&lt;/b&gt;, que fica dividida em dois segmentos: &lt;b&gt;CG&lt;/b&gt;&amp;nbsp;e &lt;b&gt;GN&lt;/b&gt;, com CG = 2(GN).&lt;/span&gt;&lt;/div&gt;

&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Todo&amp;nbsp;&lt;b&gt;triângulo isósceles&lt;/b&gt;&amp;nbsp;é também um&amp;nbsp;triângulo isoângulo, isto é, possui dois&amp;nbsp;ângulos&amp;nbsp;congruentes, que são os dois&amp;nbsp;ângulos&amp;nbsp;opostos aos lados congruentes. Chamamos esses ângulos de ângulos da base.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;
&lt;/span&gt;
&lt;br /&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Porém, essa é uma propriedade que parte da definição de&amp;nbsp;&lt;b&gt;triângulo isósceles&lt;/b&gt;, portanto, necessita de demonstração.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;
&lt;/span&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Essa propriedade traz uma condição necessária e suficiente para que um&amp;nbsp;triângulo&amp;nbsp;seja isósceles, isso é, ela diz:&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span class="mw-headline" style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
Se um triângulo tem dois lados congruentes, então esse triângulo possui os dois ângulos da base congruentes e é um&amp;nbsp;&lt;b&gt;triângulo isósceles&lt;/b&gt;.&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
Se um triângulo tem dois&amp;nbsp;ângulos&amp;nbsp;congruentes, então os dois lados opostos a esses ângulos são congruentes e esse é um&amp;nbsp;&lt;b&gt;triângulo isósceles&lt;/b&gt;.&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
Assim, vamos demonstrar que para um triângulo ser isósceles basta ele possuir dois ângulo congruentes ou dois lados congruentes.&lt;/div&gt;
&lt;/div&gt;

&lt;span class="mw-headline"&gt;&lt;span style="background-color: white; color: #222222;"&gt;&lt;span style="font-family: inherit;"&gt;Esse teorema pode ser enunciado de três formas diferentes:&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Para fazer essa demonstração precisamos mostrar primeiro que ser isósceles implica ser isoângulo.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Assim, partiremos de um triângulos isósceles qualquer e buscaremos provar que este triângulo é congruente a si mesmo, porém havendo uma correspondência nos vértices.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Para isso tomaremos duas vezes&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle \triangle {ABC}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle \triangle {ABC}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle \triangle {ABC}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/a665baeaf66c977216ac21fe3d6690a13be16b64" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 7.339ex;" /&gt;&lt;/span&gt;, tendo o cuidado de, em cada vez, alternar a ordem dos vértices da base.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Assim, podemos abstrair e pensar em dois triângulos "distintos":&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle \triangle {ABC}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle \triangle {ABC}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle \triangle {ABC}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/a665baeaf66c977216ac21fe3d6690a13be16b64" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 7.339ex;" /&gt;&lt;/span&gt;&amp;nbsp;e&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle \triangle {ACB}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle \triangle {ACB}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle \triangle {ACB}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/6433f14e4af143adef9371fde7dc29a70becdace" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 7.339ex;" /&gt;&lt;/span&gt;.&lt;/span&gt;&lt;/div&gt;

&amp;nbsp;&lt;span style="font-family: inherit;"&gt;&amp;nbsp;&lt;span style="background-color: white; color: #222222;"&gt;Visto que temos, a congruência dos dois triângulos, com isso obtemos que todos seus ângulo correspondentes são congruentes.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Agora precisamos mostrar que ser isoângulo implica ser isósceles.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Para isso partiremos de um triângulo&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle ABC}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle ABC}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="ABC" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/5e55b44cfd965fbdc7a328d5db8a35a619db0971" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 5.273ex;" /&gt;&lt;/span&gt;&amp;nbsp;qualquer que seja isoângulo, isto é, que tenha dois ângulos congruentes.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Para facilitar na demonstração, utilizaremos notação matemática com base em um triângulo&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle ABC}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle ABC}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="ABC" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/5e55b44cfd965fbdc7a328d5db8a35a619db0971" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 5.273ex;" /&gt;&lt;/span&gt;.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Então traçaremos no triângulo&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle ABC}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle ABC}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="ABC" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/5e55b44cfd965fbdc7a328d5db8a35a619db0971" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 5.273ex;" /&gt;&lt;/span&gt;&amp;nbsp;a sua bissetriz relativa ao vértice&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle A}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle A}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="A" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/7daff47fa58cdfd29dc333def748ff5fa4c923e3" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 1.743ex;" /&gt;&lt;/span&gt;.

&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Assim teremos dois triângulos:&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle \triangle {AMB}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle \triangle {AMB}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle \triangle {AMB}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/e793c7a8ec55e4897f3cd42922f9bb11884c2ec6" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 8.015ex;" /&gt;&lt;/span&gt;&amp;nbsp;e&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle \triangle {AMC}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle \triangle {AMC}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle \triangle {AMC}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/1868177a51958e2a5c35e3f4b8a2f46475f2ef9f" style="border: 0px; display: inline-block; height: 2.176ex; margin: 0px; vertical-align: -0.338ex; width: 8.018ex;" /&gt;&lt;/span&gt;, ficando fácil de verificar a congruência entre esses dois triângulos, pelo caso de congruência, lado, ângulo e ângulo oposto ao lado.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle {\overline {AM}}\equiv {\overline {AM}}\quad {\text{e}}\quad {B{\hat {A}}M}\equiv {M{\hat {A}}C}\quad {\text{e}}\quad {\hat {B}}\equiv {\hat {C}}\quad \left(LAA_{o}\right)\qquad \longrightarrow \qquad \triangle {AMB}\equiv \triangle {AMC}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle {\overline {AM}}\equiv {\overline {AM}}\quad {\text{e}}\quad {B{\hat {A}}M}\equiv {M{\hat {A}}C}\quad {\text{e}}\quad {\hat {B}}\equiv {\hat {C}}\quad \left(LAA_{o}\right)\qquad \longrightarrow \qquad \triangle {AMB}\equiv \triangle {AMC}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle {\overline {AM}}\equiv {\overline {AM}}\quad {\text{e}}\quad {B{\hat {A}}M}\equiv {M{\hat {A}}C}\quad {\text{e}}\quad {\hat {B}}\equiv {\hat {C}}\quad \left(LAA_{o}\right)\qquad \longrightarrow \qquad \triangle {AMB}\equiv \triangle {AMC}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/2de517bff722f364877816100e506398bd052e2e" style="border: 0px; display: inline-block; height: 3.509ex; margin: 0px; vertical-align: -0.838ex; width: 89.127ex;" /&gt;&lt;/span&gt;.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Com essa congruência, temos a seguinte congruência:&amp;nbsp;&lt;span class="mwe-math-element"&gt;&lt;span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="clip: rect(1px, 1px, 1px, 1px); display: none; height: 1px; opacity: 0; overflow: hidden; position: absolute; width: 1px;"&gt;&lt;math alttext="{\displaystyle {\overline {AB}}\equiv {\overline {AC}}}" xmlns="http://www.w3.org/1998/Math/MathML"&gt;&lt;semantics&gt;&lt;annotation encoding="application/x-tex"&gt;{\displaystyle {\overline {AB}}\equiv {\overline {AC}}}&lt;/annotation&gt;&lt;/semantics&gt;&lt;/math&gt;&lt;/span&gt;&lt;img alt="{\displaystyle {\overline {AB}}\equiv {\overline {AC}}}" aria-hidden="true" class="mwe-math-fallback-image-inline" src="https://wikimedia.org/api/rest_v1/media/math/render/svg/adad442cff0f05a525eeb6f99333d14ae0bd2553" style="border: 0px; display: inline-block; height: 3.009ex; margin: 0px; vertical-align: -0.338ex; width: 10.413ex;" /&gt;&lt;/span&gt;.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Assim demonstramos que ser triângulo isósceles implica ser triângulo isoângulo e que ser triângulo isoângulo implica ser triângulo isósceles.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: inherit;"&gt;Logo, temos que ser triângulo isósceles é condição necessária e suficiente para ser triângulo isoângulo.&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;

&lt;span class="mw-headline"&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Primeiramente vamos provar que, se um triângulo é isósceles, então o baricentro, o incentro, o circuncentro e o ortocentro são colineares. Para demonstrar esse teorema partiremos do que foi demonstrado acima.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span class="mw-headline"&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;

&lt;div style="text-align: justify;"&gt;
&lt;span class="mw-headline"&gt;&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Assim temos que, se tomarmos a mediana de um triângulo isósceles, temos que essa mediana é também bissetriz, altura relativa e está contida na mediatriz do triângulo.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span class="mw-headline"&gt;
&lt;div style="background-color: white; color: #222222; line-height: inherit; margin-bottom: 0.5em; margin-top: 0.5em;"&gt;
&lt;div style="text-align: justify;"&gt;
&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Isso implica qualquer ponto que pertence à mediana pertence também à bissetriz, à altura relativa e à mediatriz.&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Após demonstrar isso precisamos demonstrar a recíproca.&lt;/span&gt;&lt;/div&gt;

&lt;span style="font-family: &amp;quot;georgia&amp;quot; , &amp;quot;times new roman&amp;quot; , serif; font-size: large;"&gt;Assim, precisamos demonstrar que:&lt;/span&gt;&lt;/div&gt;
