Polygon

Concept

Polygon

A polygon consists of three or more line segments whose endpoints connect end-to-end to enclose an area. Triangles, squares and rectangles are examples of polygons.

A polygon is said to be regular if all its sides have the same length and every angle has the same measure. A polygon which is not regular is irregular. There is no upper limit to the number of line segments that can form a polygon.

Polygons with more than four sides are often named with the Greek prefix for the number of sides, followed by -gon. Try it out yourself below by pressing \boxed{\phantom{|}\hspace{-0.085cm}\textcolor{#009600}{⬆}} and \boxed{\phantom{|}\hspace{-0.085cm}\textcolor{#FF0000}{⬇}} to increase or decrease the number of sides.
