What is Meant by Polygon?

In mathematics, a polygon is a closed two-dimensional flat-shaped figure. It does not have a curved surface. A polygon can be classified as regular polygons and irregular polygons. The regular polygons have equal sides and angle measurement, whereas the irregular polygon has different side and angle values. The polygon with the least number of sides is a triangle and the polygon with “n” number of sides is called n-gon. The perimeter and the area of the regular polygon formula are given as follows:

Area of regular polygon = [s2n]/[4tan(180/n)] square units

The perimeter of regular polygon = n × s units

Where

“n” is the number of sides

“s” is the side length
