All the interior angles of a regular pentagon are congruent, measuring 108 degrees each, while the sum of all angles in any pentagon is 540 degrees.

    The term "pentagon" comes from the Greek words "pente" meaning "five" and "gonia" meaning "angle." The concept of a pentagon has various applications in mathematics, geometry, architecture, and design. It serves as a fundamental building block for constructing more complex shapes, such as polyhedra or tessellations. Pentagons are often encountered in nature, such as in the structure of some seeds, leaves, and starfish.
