What is a 2 sided shape called? Digon. In geometry, a digon is a **polygon** with two sides (edges) and two vertices. Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be easily visualised in elliptic space.
