Learn about polygon and also **types of polygons**. In lower class, mathematics polygons are a very important topic. So every student should know about polygon definition and various **types of polygons**. The meaning of **polygon** is poly meaning is many and gon meaning is sides.

A Polygon definition can be defined as a simple closed figure which is bounded by line segments. For getting a closed figure do you know how many line segments we need? To draw a closed figure we need a minimum of three line segments. With two line segments, we get open figure only not a closed figure. So we can draw a closed figure by only with 3 line segments. Based on the number of line segments we have **different types of polygons**. Now we will study all of that **different polygons**.

**Names of different types of polygons:**

•A polygon which is bounded with three line segments is called a triangle.

•A polygon bounded with four line segments is called quadrilateral. In quadrilateral, we have different types based on sides and angles like a square, rectangle, trapezium, rhombus, kite and parallelogram, and so on.

•A polygon which is bounded with five line segments is called Pentagon.

•A polygon with six line segments is called Hexagon.

•A polygon with seven line segments is called Heptagon or sometimes we can also call as Septagon.

•A polygon with eight line segments is called Octagon.

•A polygon with nine line segments is called Nonagon.

•A polygon with ten line segments is called Decagon.

Up to ten line segments we have special names for a polygon. But we don’t have any special name for a polygon with 11 or 12 or 13 or … sides. But we can call them as

**Number of ****Side’s Polygon Name**

11 11-gon

12 12-gon

13 13-gon

14 14-gon

15 15-gon

And so on we can give the names for polygons according to sides. Hope all the definitions of *types of*** polygons** are very clear.
