Testing a Polygon for Convexity and Self-Intersection
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Drag the black vertices to change the polygon. The Demonstration tests for its convexity or self-intersection. Self-intersection always implies non-convexity, but not the other way around.
