WebAnswer by stanbon (75887) ( Show Source ): You can put this solution on YOUR website! How many diagonals does a regular n-gon have? ---- The n-gon will have n vertices. --- Every pair of vertices determines a line segment. You have nC2 = n (n-1)/2 pairs of vertices. So you have n (n-1)/2 line segments determined. ----------------------- WebThe formula would be: d = n* (n-3)/2 where. d = number of diagonals. n = number of sides of the polygon. Example: number of diagonals in a hexagon would be: (6 * 3) / 2 = 9. I verified this is correct. For your 12 sides figure, the number of diagonals would be: WebDodecagon has 12 sides and 12 vertices.
