Constructing Regular Polygons With 6, 8, or 10 Sides

How to construct one of the regular polygons with 6, 8, or 10 sides?

Select one of the regular polygons with 6, 8, or 10 sides, and determine how to construct it using just a compass and a straight edge (you should not need to use any length measurements). The term “straight edge” is used rather than ruler because length measurements are not used in this activity (other than to sometimes determine how far to open your compass). Write a clear, concise description of your method so that anyone else can follow it without additional information. Include step-by-step images, which could be photos and diagrams.
