A New Angle on an Old Construction

It’s well known that exact straightedge-and-compass construction of a regular n-gon is impossible for most values of n. I’ll introduce a historical technique for approximating a regular n-gon that works (more or less) for any value of n. Finally, I’ll introduce a slight variation — original as far as I know — that improves the construction’s accuracy. The material is very accessible! The only mathematical background needed is a little algebra and trigonometry.
