As you all might be aware that the SLT is not that easy to prove, so what I meant was can anyone show us the most innovative proof there is of the SLT. Some by Mowaffaq Hajja are really very nice!

I don't think so. Just refer to Challenges.

What I meant was that it definitly is nt Pythagoras' to prove, it needs a certain amount of creativity!

Any triangle with two angle bisectors of equal lengths is isosceles.

Well the most innovative proof according to me is this one given by a French ENgineer and Geometer which requires the construction of a parallel to one of the angle bisectors through the opposite vertex and extending both outside the trianglem to get a parallelogram and proving by contradiction tht the triangle is isoscles.
