WebApr 8, 2024 · As described above, the number of diagonals from a single vertex is three less than the number of vertices or sides, or (n-3). There are a total number of N vertices, which gives us n(n-3) diagonals. But each diagonal of the polygon has two ends, so this would count each one twice. So as a final step we need to divide by 2, for the final ... WebThe number of triangles in each polygon is two less than the number of sides.
