In this picture, the middle three polygons are concave but they can be divided. The middle polygon of the three does not contain a point from which rays can be drawn to touch any part of the polygon without leaving it, but the other two do.
Besides just saying lol they're all concave why does it matter is there a term for the property I'm trying to describe?
