Triangle Divided (Posted on 2010-04-15) Difficulty: 2 of 5

Let P be a point in the interior of an equilateral triangle.

Three line segments connect P with the vertices of the 
triangle and three line segments connect P perpendicularly
to the sides of the triangle.

These six line segments divide the triangle into six smaller
triangles that surround P.

If u, v, w, x, y, and z denote the areas of the triangles 
around P in that order, then prove that

                     u + w + y = v + x + z.

This was my first thought also.

I did not use this fact in my proof, but that does not mean that it could not be used in an alternate proof.
