Desafio geométrico que parece simples, mas exige atenção aos detalhes. O ângulo externo indicado mede 110°. Como ele forma um par linear com o ângulo interno da base do triângulo, calculamos o seu suplementar. Ângulos suplementares somam 180°, portanto 180° − 110° = 70°. Esse ângulo de 70° é um dos ângulos internos do triângulo. Observando as marcações, percebemos que o triângulo é isósceles, pois possui dois lados congruentes. Em um triângulo isósceles, os ângulos da base são congruentes. Log

Você sabia que o losango é um "primo" muito próximo do paralelogramo? 🤔 Hoje resolvi um exercício prático para mostrar que as propriedades que a gente já conhece — ângulos opostos congruentes e adjacentes suplementares — funcionam perfeitamente aqui também! Vem conferir essa correção e tirar suas dúvidas de uma vez por todas. Matemática fica muito mais simples quando a gente entende as conexões, né? Bora aprender! #MatemáticaComLucas #GeometriaPlana #Losango #DicasDeMatemática #estudoeficiente

Desafio: Mostre que você se garante mesmo! Sem fazer conta, somente usando duas folhas quadradas e congruentes, determine essa série geométrica!
