Сторона  АВ вписанного угла проходит через центр окружности, значит эта стороны является диаметром окружности. Следовательно, любой вписанный угол, опирающийся на диаметр, равен 90°. Тогда треугольник АВС - прямоугольный, с прямым углом С. Следовательно, данный нам вписанный угол будет острым, так как в треугольнике не может быть двух прямых углов.
