Diagonals of a Polygon
You now know how to identify the diagonals of any polygon what some real-life examples of diagonals are and how to use the formula of Diagonals nn 3 2 o f D i a g o n a l s n. Basically it is used when something need to be proven forall n in mathhbbN.

. Suppose there is a polygon and it is having with having total of 20 diagonals then by the help of formula and doing the evaluation find out the total number of. In Greek poly means many and gon means angle. The simplest polygon is a triangle which has 3 sides and 3 angles which sum up.
Lets develop an intuitive method for counting number of diagonals of a polygon--it will come out to be nn-32 in which n is the number of sidesYour supp. Therefore finding the number of diagonals in a polygon with n-sides can be unfeasible.
