            A five-sided shape is called a pentagon. A pentagon may be regular (all sides and angles are the same) or irregular (the opposite of regular).

            In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
