Ответ:

существует

Объяснение:

Четырехугольник называется выпуклым, если он расположен в одной полуплоскости относительно прямой, содержащей любую его сторону.

к ним относятся все изучаемые четырехугольники школьного курса: ромб, трапеция, параллелограмм, квадрат.

с углами 110 и 70 могут быть равнобокая трапеция или параллелограмм.
