Answer»

Step-by-step explanation:

A polygon has EXACTLY one internal ANGLE per vertex. If every internal angle of a simple polygon is LESS than 180°, the polygon is called convex. In contrast, an EXTERIOR angle (also called an EXTERNAL angle or turning angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side.
