Which of the following polygons has five sides?

A polygon with five sides is known as a pentagon. The term "pentagon" is derived from the Greek words "penta," meaning five, and "gon," meaning angle. This classification is essential in geometry, as polygons are defined by the number of their sides. A pentagon specifically has five edges and five vertices.

In contrast, a quadrilateral has four sides, a triangle has three sides, and a hexagon has six sides. Understanding these definitions helps clearly differentiate between various types of polygons and contributes to a broader comprehension of geometric shapes and their properties.
