How many diagonals can be drawn in an octagon
WebIn the case of an octagon, there are 8 sides. Therefore, n = 8. So, let us substitute 8 in the formula: (n - 3) = 8 - 3 = 5. This shows that 5 diagonals can be drawn one vertex of an … 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.
