FInd the number of diagonals that can be drawn for a pentagon.


To do: Find the number of diagonals that can be drawn for a pentagon.


Solution:

The number of diagonals of any polygon can be calculated using the formula $n\times\frac{n−3}{2}$

where n is the number of sides

A pentagon has 5 sides

So number of diagonals = $5\times\frac{5-3}{2}$

                                             = 5

 

Therefore , 5 diagonals can be drawn for a pentagon.
