Ângulos no transferidor de 360º - Construção

Um ângulo é o conjunto de pontos formados por duas semirretas (lados do ângulo) que possuem o mesmo ponto de partida (vértice do ângulo).
O ângulo é uma região delimitada por duas semirretas. Para medi-lo, há duas possíveis unidades: grau ou radiano. De acordo com a sua medida, ele pode ser classificado em nulo, agudo, reto, obtuso, raso, côncavo e uma volta completa.[br]Com base nesse conceito desenhe um ângulo de 50º, seguindo os passos abaixo:[list][*]Clique no comando semirreta [img]data:image/png;base64,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[/img]e desenhe um ângulo com abertura 50º, partindo do comando [img]data:image/png;base64,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[/img](Marcar um ângulo sobre a reta) do centro do transferidor, que representará o vértice do ângulo.[/*][/list][list][*]Clique no comando transferidor e confira se o ângulo corresponde a medida indicada de 50º, caso não esteja com essa amplitude correta corrija e depois desmarque o comando transferidor e verifique a abertura do ângulo que correspondente exatamente 50º.
