Web(diagonals to itself and one either side are not counted). Formula for the number of diagonals. As described above, the number of diagonals from a single vertex is three less than the the number of vertices or sides, or (n-3). There are N vertices, which gives us n(n-3) diagonals But each diagonal has two ends, so this would count each one twice. WebWell start with the first step: prove, that n ( n − 3) 2 is the number of diagonals for the smallest possible polygon. In this case it is n -polygon, where n = 3. In the second step assume, that k ( k − 3) 2 is the number of diagonals for k -polygon and you must show that ( k + 1) ( k + 1 − 3) 2 is the number of diagonals for ( k + 1) -polygon.
