Master Classify polygons as convex and concave

The video tutorial explains how to determine if a polygon is convex or concave. Convex polygons have sides that, when extended, do not cross the interior, while concave polygons have sides that do. The method involves extending each side of the polygon; if any extension enters the interior, the polygon is concave. The video provides examples of both convex and concave polygons to illustrate these concepts.
