Math Forum Project: Dodecagon from a Circle

This month's free project on the Math Forum shows how to start with a circle, add some more circles and construction lines . . .

The Student Version has a question about the number of circle "sides" needed to start with, to create a dodecagon. The Teacher Version has the answer! Enjoy.
