What is a pentagon ?

Pentagon with five sides and angles. A pentagon, a five-sided polygon, is famed for its role in nature (starfish, flowers) and human design (the Pentagon building). Regular pentagons, with their golden ratio proportions, are used in military insignia, sacred symbols, and tessellation studies, blending aesthetics and mathematics. The area formula for a regular pentagon is: Area = (5/2) × side × apothem.
