What is the name of a polygon with 5 sides?

The polygon with five sides is called a pentagon. This term is derived from the Greek words "penta," meaning five, and "gonia," meaning angle. Therefore, a pentagon specifically refers to a geometric figure that has five straight sides and five angles.

In contrast, a hexagon features six sides, a quadrilateral has four sides, and a triangle has three sides. Each of these shapes is classified according to the number of sides it has, and understanding these classifications is essential for recognizing the characteristics that define different polygons.
