Which term describes a polygon with five sides?

A polygon with five sides is specifically known as a pentagon. This term comes from the Greek words "penta," meaning five, and "gon," meaning angle. Each vertex in a pentagon connects to two other vertices, creating five angles and five sides. This makes the pentagon a significant shape in both geometry and various applications, such as architecture and design.

For further clarity on the other terms: a hexagon has six sides, a quadrilateral has four sides, and a heptagon has seven sides. Understanding these different types of polygons helps in recognizing their properties and applications in various mathematical contexts.
