Polygon number of diagonals
WebThere is a formula for determining the number of diagonals in a polygon of n sides, and that is n(n-3)/2. In the present case since there are 170 diagonals, WebAnswer (1 of 4): (n)(n-3)/2 where n is the number of vertices. A square has (4)(1)/2 = 2 diagonals; a pentagon has (5)(2)/2 = 5 diagonals; a hexagon has (6)(3)/2 = 9 diagonals; a …
