All polygons have 3 essential properties: All polygons can be broken down into parts. In contrast, a concave polygon is any polygon that has at least one angle whose measure is greater than 180 degrees. It takes at least 3 straight lines to enclose some area of space. j Polytopes of a particular dimension n can be understood as being constructed out of elements of dimension n1. Hexagonal Prism. The area A of a simple polygon can also be computed if the lengths of the sides, a1, a2, , an and the exterior angles, 1, 2, , n are known, from: The formula was described by Lopshits in 1963.[7].
