What is a polegon?

Answer 1

First of all it is a 'polygon' , NOT a 'polegon'.

A polygon is a plane two dimensional figure of any number of sides.

Answer 2

A polygon is a plane figure whose boundary is formed by straight lines. The simplest example is a triangle. A square, rectangle, kite, etc are common 4 sided polygons. Polygons can have angles that are greater than 180 degrees (reflex angles), so a 5 pointed star is a ten sided polygon. There is no limit to the number of sides a polygon can have.

If all the sides and angles of a polygon have the same measures, it is called a regular polygon.
