Prove or disprove, that the points of intersection of the adjacent trisectors of the angles of any triangle are the vertices of an equilateral triangle. (In other words, that for any yellow triangle, the green triangle will be equilateral, given that the thinner lines trisect their respective angles.)

I decided to re-phrase the problem a little, and make it live. Now, anyone who has proof or disproof (Jim) can submit it for everyone to see.
