WebWhile the octagon has five diagonals and the nonagon six diagonals, both the octagon and the nonagon have only three different types of diagonals as described in the earlier Instructables. Each diagonal can be regarded as forming the base of an isosceles triangle whose legs are radii of the polygon's circumscribed circle. WebA diagonal is a pair of these points which are more than 1 apart, and it is parallel to an edge if their difference is odd. It's easier to pick diagonals which are not parallel - because …
