Full Answer

In addition to having five sides, the sides must also form a closed shape. Sides also must be straight. Pentagons can be regular or irregular. An irregular pentagon refers to any pentagon where all sides are not equal, which consequently means that their angles are not equal, either. Other closely related shapes to pentagons include four-sided shapes, quadrilaterals, and six-sided shapes, which are called hexagons.
