A polygon is a closed plane figure bounded by straight line segments. The line segments are called the sides of the polygon, and the points at which they intersect are called vertices. A polygon has the same number of sides as it has vertices. Polygons are classified according to the number of sides they have. A polygon with n sides is called an n-gon. Thus the polygon shown below is called an 9-gon. Nonagon
Here are some more polygons that you may be familiar with. It should be recognisable at this stage that polygons surround us in our every day lives whether it be the face of the computer screen that you are looking at right now or the shape of the matt that your mouse rolls on. Other Polygons
Here we have an 8-gon or more regularly known as an octagon. This is yet another polygon that we see every day that we take a drive in a car.

Polygons can be broken into two distinct categories 1) Regular, 2) Irregular.
