Work Step by Step
(a) In part a, the angle C is an interior reflex angle because the measure of the interior angle is between $180^{\circ}$ and $360^{\circ}$
(b) In part b, the angle B and the angle D are interior reflex angles because the measure of the interior angles is between $180^{\circ}$ and $360^{\circ}$
