1/2*(n2-3n) = number of diagonals
1/2*(202-60) = 170 diagonals
The five sided Polygon has 5 diagonals
Number of sides minus 2 equals the number of triangles within 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

A 7 sided polygon has 14 diagonals
The five sided Polygon has 5 diagonals
Number of sides minus 2 equals the number of triangles within the polygon.
Number of diagonals = 1/2*(n2-3n) where n = the number of sides of the polygon.
Number of sides minus two equals number of diagonals drawn from one vertex.
