# PLANES FIGURES POLYGONS

Welcome to Class !!

In today’s Basic Technology class, We will be discussing Plane Figures (Polygons). We hope you enjoy the class!

## PLANES FIGURES POLYGONS

A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two other sides but only at their endpoints. The sides must be noncollinear and have a common endpoint.

A polygon is usually named after how many sides it has, a polygon with n-sides is called an n-gon. E.g. the building which houses the United States Department of Defense is called pentagon since it has 5 sides.

Sides                  Polygon

3                           triangle

5                           pentagon

6                           hexagon

7                           heptagon

9                           nonagon

10                        decagon

A regular polygon is a polygon in which all sides are congruent and all the angles are congruent.

We have come to the end of this class. We do hope you enjoyed the class?
