How many sides does a Pentagon have?

A pentagon has five sides, which is the defining characteristic of this geometric shape. The term "pentagon" itself is derived from the Greek words "penta," meaning five, and "gon," meaning angle or side. Therefore, any polygon that has five sides and five angles is classified as a pentagon. This recognition is essential in geometry, particularly when categorizing different types of polygons based on the number of their sides. Understanding the terminology and properties of shapes like the pentagon aids in developing a foundational knowledge of geometry that is applicable in various fields, including engineering and architecture.
