Question

how to solve this problem

Answer 1

Answer:

Step-by-step explanation:

an hexagon is a polygon with 6 sides that is n = 6. thus the number of diagonals is equal to 6(6 - 3)/2 = 9.

Answer 2

Hii !
The formula to find diagonals in a given n sided polygon has been given to you
So if you want to find out no of diagonals in hexagon that is a six sided polygon
No.of diagonals = 6*(6-3)/2 = 9

The formula for no.of diagonals is derived from combinatorics with advanced geometry.
