How many diagonals are there in hexagon
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.
