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. WebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2.
