МатематикаВопрос:
The sum of the angles of a convex quadrilateral is 360 degrees. A. True B. False
Ответ:
Обоснование:
Это утверждение верно. Сумма углов любого выпуклого четырёхугольника всегда равна 360 градусам. Это можно доказать, разделив четырёхугольник на два треугольника диагональю. Сумма углов двух треугольников будет $$180^\text{o} + 180^\text{o} = 360^\text{o}$$, что и составляет сумму углов четырёхугольника.
Ответ: A. True
