МатематикаВопрос:
The sum of two opposite angles of a quadrilateral does not exceed 180 degrees. A. True B. False
Ответ:
Обоснование:
Это утверждение неверно. У выпуклого четырёхугольника сумма двух противоположных углов может быть как меньше, так и больше 180 градусов, или равна 180 градусам. Например, в прямоугольнике сумма противоположных углов равна 180 градусам. А в остроугольном четырёхугольнике, где все углы меньше 90 градусов, сумма противоположных углов может быть меньше 180 градусов, а в тупоугольном — больше.
Ответ: B. False
