WebMay 7, 2015 · I guess the answer is: C ( n, n − 3) / 2 since for n -sided polygon,there are n vertices, and for each vertex, it cannot form diagonal with the adjacent points and itself. So, each vertex can form n − 3 points. And half of the vertices have repeated diagonals and we need to divide by 2.

For the hexagon we have A=4 x 6=24. Again note the interior smaller hexagon created by the procedure. In this case the sub-areas consist of six qudrangles, six larger isosceles triangles and 12 small right triangles. For a seven-sided polygon ( heptagon ) we find D=14 and A=50. e national land and property gazetteer nlpg
