# Polygon

What is a polygon?

A simple closed curve made of three or more line-segments is called a polygon. A polygon has at least three line-segments.

The line-segments of a polygon are named by the sides in it. Poly means many and gon means sides. Thus a polygon has many sides.

The different polygons having definite number of sides are given names according to the number of sides.

(i) A polygon with three sides is called a triangle.

(ii) A polygon with four sides is called a quadrilateral.

(iii) A polygon with five sides is called a pentagon.

(iv) A polygon with six sides is called a hexagon.

Thus a polygon is given its name on the basis of the number of its sides.
