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 becomes: 8 (8-3)/2. This simplifies to: 20. Therefore, there are 20 diagonals 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 … 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.
