5. ## Triangle, trisected

Correct. Good job. I wonder if there is a proof of this that is not overly complex? Edit: Well, No. I just found the proof, and it's not beautiful for its simplicity. You start with the Law of Sines, and 2 1/2 pages later you have a symmetrical expression for one side. "Do not try this at home." oh i am so sorry .....i mistook it for the eulers line....my bad...

17. ## Triangle, trisected

You're right about the bisector case. But for the trisector case there is more than one point. In fact there are three places where a trisector of one angle first intersects a trisector of one of the other angles. And there is something special about those three points.
