МатематикаВопрос:
Any isosceles triangle has an axis of symmetry.
Ответ:
Ответ:
1. Верно
Обоснование:
У любого равнобедренного треугольника есть одна ось симметрии – это биссектриса угла при вершине, проведенная к основанию. Она делит треугольник на два равных зеркальных прямоугольных треугольника.
