Given a partition of a square into n triangles of equal area, prove that n is even.

(In reply to re(5): Part I - notation by Richard)

Richard, you have a point.  My first post should have been accompanied by some kind of explanation. 

Arbitrary disruption was not my intent.  I simply noticed that the problem had been posted on the site for a few hours already, without eliciting a single comment.

My first post was intended to 1) let Josh70679 know that someone was at least looking at his problem; 2) provide a starting point for anyone who actually understands p-adic valuation and p-adic topology (I don't understand well enough to come up with a solution on my own).

I could have included the above explanation along with my post.
