The next diagram reveals how to utilize Perfectagøn to create an enneagon.
The Perfectagøn method also results in a very accurate measurement for the side length of the enneagon, which again makes Perfectagøn a perfect choice for creating regular polygons that are normally considered difficult or impossible.
By now it should be obvious that Perfectagøn is the perfect choice for drawing regular polygons, and one more example will help illustrate the elegant power of Perfectagøn.
