This article is about the pentagon blended with a digon. For the skew polygon with 5 vertices, see Pentagonal-pentagrammic coil.

The skew pentagon is a regular skew polygon in 3D Euclidean space. Despite its name it has 10 sides and 10 vertices. It is the result of blending a pentagon with a digon. Since the pentagon is not 2-colorable the result has twice as many vertices and edges as the pentagon. It consists of the 10 lateral edges of a pentagrammic antiprism.
