An interior angle is an angle inside a shape. example: pentagon. a pentagon has 5 sides, and can be made from three triangles, so you know what.. its interior angles add up to 3 × 180° = 540° and when it is regular (all angles the same), then each angle is 540° / 5 = 108° (exercise: make sure each triangle here adds up to 180°, and check that the pentagon's interior angles add up.
