Different Types of Polygons
The different types of polygons are discussed here.
In
any polygon a pair of sides that are inclined to each other meet at a
point. This point is called a vertex of the polygon. In the polygon
there are as many vertices as there are sides.
Definition of Polygon:
A polygon is a plane figure that is made by joining the line segments where each line segment meets exactly two other line segments.
The intersection point of two line segments is called the vertex of the polygon.
Polygons are classified according to their number of sides.
Polygon - Triangle:
The triangle has 3 sides and 3 vertices.

Polygon - Quadrilateral:
The quadrilateral has 4 sides and 4 vertices.
