Just find two! (Posted on 2005-04-27)

Given a triangle ABC, how can you find a point P on AC and a point Q on BC, such that AP=PQ=QB?

N.B. A construction method is sought, and only compass and straightedge are allowed.

Um, sorry. Of course X and Y are at infinity. What I meant to say was to construct a perpendicular at M, not X. I have edited my solution to correct this.
