Properties of a concave hexagon


A regular or equilateral hexagon is a polygon that consists of six vertices and six sides. If all six sides are the same length, we speak of an equilateral hexagon. Even if all the angles at the six corners are the same size, the hexagon is called a regular hexagon. The concave hexagon described on this page is equilateral but not regular because all sides are the same length, but it has different angles.

A concave hexagon is an equilateral polygon with six sides in which at least one of the interior angles is greater than 180°.
