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.

(In reply to re(6): The next problem after this... by Happy)

>>1782^12 + 1841^12 = 1922^12 (it works out on the calculator)
So then what was the theorem? That it can't be done? If so, how does it come out with the above case?
