A polygon is convex
if all of its edges go outwards rather than inwards.
A convex polygon is a simple polygon whose interior is a convex set.
The following properties of a simple polygon are all equivalent to
- Every internal angle is less than 180 degrees or equal to 180
- Every line segment between two vertices of the polygon does
not go exterior to the polygon (i.e., it remains inside or on
the boundary of the polygon).
