It is: 0.5*(144-36) = 54 diagonals
The five sided Polygon has 5 diagonals
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
The formula is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon
A polygon with 14 diagonals will have 7 sides

A 7 sided polygon has 14 diagonals
The five sided Polygon has 5 diagonals
Number of diagonals = 1/2*(n2-3n) where n = the number of sides of the polygon.
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
