Web22 okt. 2024 · But, each diagonal is counted twice, once from each of its ends. Thus, there are 20 diagonals in a regular octagon. Using the formula, to draw a diagonal, you have to select two vertices out of n, but you cannot draw diagonal by joining the adjacent vertex. Number of diagonals = nC2 – n , where n is the number of sides of the polygon. Web22 jun. 2024 · Try It! Since for an n-sided convex polygon, from each vertex, we can draw n-3 diagonals leaving two adjacent vertices and itself. Following this way for n-vertices, there will be n* (n-3) diagonals but then …
