How many diagonals can be drawn in an octagon

WebApr 7, 2024 · The formula for calculating the number of diagonals in an octagon is: n (n-3)/2. Where n is the number of sides of the polygon. In this case, n is equal to 8, so the formula … WebA dodecagon can be split into a series of triangles by the diagonals that are drawn from its vertices. The number of triangles that are formed by these diagonals can be calculated with the formula: (n - 2), where n = the number of sides. In this case, n = 12. So, 12 - 2 = 10. Therefore, 10 triangles can be formed in a dodecagon.
