How to build a regular polygon?

Method

general.

1. Draw a circle, which will be inscribed regular polygon.
   

2. AN We trace the vertical diameter and divide it into as many equal parts as
   sides have the regular polygon, in this case 7 equal parts. To divide the diameter
   use Thales' Theorem.
   

3. With center A and radius AN, we draw an arc with center at N and AN radio.
   We draw another arc with the same radio but with center N. Both
   arcs intersect at point P.
   

Uniting

4. P pairs divisions diameter until it intersects the circumference
   B, C and D.
   

5. Finally, work by mirroring the left side. We are determined, in this
   case, the regular heptagon.
   

Polygonal
Stars.

To build a star polygon, we use the same general method of
constructions of regular polygons, but instead of joining the vertices
each one, we join two two, three, three, four to four, and so on.

And with a little imagination ... from the construction of a hexagon ...

Or a decagon ...
