WebQuadrilaterals can only have 1 such diagonal. Drawing in the other one would intersect the first one, and they're called "non-intersecting" for a reason. If we take a pentagon, we can draw 2 diagonals that don't intersect. The key is to draw just enough to separate the polygon into all into triangles. WebSolution: The number of diagonals of a polygon of n sides, is given by n (n-3)/2. Here, n = 13, so the 13-gon has 13 (13–3)/2 = 65 diagonals.
