How many diagonals in a 7 sided polygon
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. WebDiagonals: A nonagon has 27 diagonals, which are lines that connect non-adjacent vertices of the polygon. The formula to calculate the number of diagonals in a nonagon is n (n-3)/2, where n is the number of sides. Symmetry: A nonagon has nine lines of symmetry, which divide the polygon into nine congruent parts.
