Definition on Polygon

Introduction to polygon

In this section let me help you on polygon definition.

Definition of Polygon:

A polygon is a closed plane figure formed by three or more sides. It has equal number of sides and vertices. Word Polygon is basically from Latin - Greek polugōnon means figure with many angles. In simple words, a closed two dimensional figure having three or more straight sides is a polygon. Exactly two sides meet at every vertex.

Example: Below is the figure of four sided polygon:

A polygon with all sides equal and all interior angles equal is called as Regular polygon, otherwise it is irregular. Specific polygons are named according to the number of sides, such as triangle, pentagon, etc.. this can also help us on vertices definition

Internal angles :-

A regular polygon is a polygon which has all the sides equal and all the angles equal. Regular polygons may be convex or Complex polygon. A regular n-sided polygon has rotational symmetry of order n. All vertices of a regular polygon lie on a common circle (the circumscribed circle), i.e., they are concyclic points.Also, a regular polygon can have an inscribed circle or incircle.
