МатематикаВопрос:
The sum of the angles of a right-angled triangle is 90 degrees. A. True B. False
Ответ:
Обоснование:
Это утверждение неверно. Сумма углов любого треугольника, включая прямоугольный, всегда равна 180 градусам. В прямоугольном треугольнике один угол равен 90 градусов, а сумма двух других острых углов равна 90 градусам.
Ответ: B. False
