Fold an Equilateral Triangle from a Circle

You can easily fold an equilateral triangle starting with a circle.

Steps

1. Draw a circle on a piece of paper with a compass and cut it out.
   
2. Fold any point on the circumference to the center.
   
3. Fold again so the fold touches the corner of the first fold and a point on the circumference touches the center.
   
4. Fold the final section in to the center.
