WebTo find the number of diagonals in a polygon, we multiply the number of diagonals per vertex ( n − 3) (n-3) (n− 3) by the number of vertices, n n n , and divide by 2 (otherwise each diagonal is counted twice); n ( n − 3) / 2 n (n-3)/2 n(n− 3)/2 Therefore, for a 20-sided polygon, there will be 190 lines and 170 diagonals. WebOct 22, 2024 · Thus, there are 20 diagonals in a regular octagon. Using the formula, to draw a diagonal, you have to select two vertices out of n, but you cannot draw diagonal by joining the adjacent vertex. Number of diagonals = nC2 – n , where n is the number of sides of the polygon. For octagon, n = 8. Hence, Number of diagonals = 8C2 – 8 = 28 – 8 = 20.
