### What is Meant by Regular Polygon?

In geometry, a polygon is a two-dimensional figure, made up of straight-line segments. Based on the angles and sides, as well as the symmetry, convexity some other properties, the polygons are classified. Thus, there are different types of polygons in general. If the length of all the sides are equal, then the polygon is called a regular polygon. An equilateral triangle is an example of a regular polygon with 3 sides, a square is a regular polygon with 4 sides. Other polygons include pentagon, hexagon, heptagon, and so on as given the table below.

 Polygon Name Number of Sides 3 sided Polygon Trigon (or) Triangle 3 4 sided Polygon Tetragon (or) Quadrilateral 4 5 sided Polygon Pentagon 5 6 sided Polygon Hexagon 6 7 sided Polygon Heptagon (or) Septagon 7 8 sided Polygon Octagon 8 9 sided Polygon Nonagon 9 10 sided Polygon Decagon 10 N sided polygon n – gon n
