bullet::::- an angle that is part of a simple polygon is called an "interior angle" if it lies on the inside of that simple polygon. a simple concave polygon has at least one interior angle that is a reflex angle.

bullet::::- the supplement of an interior angle is called an "exterior angle", that is, an interior angle and an exterior angle form a linear pair of angles. there are two exterior angles at each vertex of the polygon, each determined by extending one of the two sides of the polygon that meet at the vertex; these two angles are vertical angles and hence are equal. an exterior angle measures the amount of rotation one has to make at a vertex to trace out the polygon. if the corresponding interior angle is a reflex angle, the exterior angle should be considered negative. even in a non-simple polygon it may be possible to define the exterior angle, but one will have to pick an orientation of the plane (or surface) to decide the sign of the exterior angle measure.
