WebOct 6, 2016 · So 18/2=9 diagonals for a hexagon. So your 20 sided polygon (called an icosagon). 20 vertices. you can't draw from the vertex to itself or either of the 2 consecutive vertices....leaving 17 vertices from each vertex. So 20vertices * 17 diagonals divided by 2 for the repetitions = 170 diagonals. In general, if n is the number of sides, then n is ... WebNov 13, 2005 · A quadrilateral has at most one point of intersection. A pentagon has 5. A hexagon has 15. Suppose an n-gon has D (n) diagonals. Then an n+1-gon has D (n)+n-1 diagonals. You can see this if you draw an n-gon, then see what happens when you add a point to make it an n+1-gon.
