Skew polygon

From Wikipedia, the free encyclopedia

In geometry, a skew polygon is a polygon whose vertices do not lie in a plane. Skew polygons must have at least 4 vertices.

The interior surface (or area) of such a polygon is not uniquely defined, although can be considered as a minimal surface problem like the form of a soapy film inside of a wire frame.
