WebQuestion 750743: if polygons of n sides has 1/2n(n-3) diagonals, how many sides will a polygon with 65 diagonals have? is there a ploygon 80 diagonal Answer by MathLover1(19943) (Show Source): You can put this solution on YOUR website! Let be the number of sides = number of vertices. WebNov 19, 2016 · The real answer is 54. Just because a dodecagon has 12 sides doesn't mean it has 12 diagonals because you can go either which way. To get a answer for this you can: 1. Multiply 12 and 9. You should get 108. 2. Then divid it by 2. You should get 54. That is correct: The general rule for a polygon with n sides is that it has n* (n-3)/2 diagonals.
