What is the difference between concave and convex polygons

The video tutorial explains the difference between concave and convex polygons. It demonstrates how to identify each type by extending the exterior lines of a polygon. If the extended lines do not intersect the interior, the polygon is convex. If they do intersect, it is concave. The tutorial uses the analogy of a cave to help remember that concave polygons have lines intersecting inside.
