Nonagons and other polygons can also be classified as either convex or concave. If all interior angles of a nonagon are less than 180°, it is convex. If one or more interior angles is larger than 180°, it is concave. A regular nonagon is a convex nonagon. Convex nonagon. WebA square’s two diagonals divide each other into two equal segments. A square’s two diagonals divide each of the square’s four right (90-degree) angles into two equal 45-degree angles. Opposite sides of a square are parallel.
