Feynman's Triangle Problem

this triangle result puzzled famous physicist Richard Feynman in a dinner conversation: For a triangle ABC in the plane, if each vertex is joined to the point (1/3) along the opposite side (measured say anti-clockwise), then area ABC = 7 x area UWV (the inner triangle formed by these lines).
