WebNonagons are geometric shapes with nine sides. Like any polygons, nonagons can be regular or irregular. Regular nonagons have nine sides of equal length and nine angles of equal degree measurement. All angles … Although a regular nonagon is not constructible with compass and straightedge (as 9 = 3 , which is not a product of distinct Fermat primes), there are very old methods of construction that produce very close approximations.
