How many sides does a Pentagon have?

A pentagon is defined as a five-sided polygon. The term "pentagon" is derived from the Greek words "penta," meaning five, and "gon," meaning angles or sides. Therefore, a pentagon must have exactly five edges and five vertices. This geometric shape is commonly recognized in various contexts, such as architecture and design, where the classic form is often associated with the specific five-sided figure used in the emblem of the United States Department of Defense. Understanding the properties of different polygons not only aids in geometry but also in real-world applications where spatial awareness is critical.
