The five sided Polygon has 5 diagonals
0.5*(n2-3n) where n is equal to the number of sides of the polygon
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

0.5*(n2-3n) where n is equal to the number of sides of the polygon
A 7 sided polygon has 14 diagonals
Number of diagonals = 1/2*(n2-3n) where n = the number of sides of the polygon.
38 diagonals
It has 20 diagonals
