How can you divide an angle into 3 equal angles? You may only use a straightedge and a compass to achieve this.

(This means : You have an angle A, you divide Angle A into 3 Angles B,C,D. And B=C=D=A/3)

Note: vohonam clarified that the problem actually only gives you a straightedge, not a ruler.

Woo-hooo! We reached problem number 100 in our database. Huge thanks go to vohonam, and anyone else who has or will contribute problems to this site.
