Welcome to Class !!

We are eager to have you join us !!

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


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

4                           quadrilateral

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.
