B Bisecting angle proof

  1. Nov 11, 2015 #1
    Hi, guys, i made an exercise, can you prove this?
    If you have 5 free minutes, try it, i hope you'll like it!
    It's my first own exercise, so I would like some feedback, too.
    AD= bisecting(splits angle in 2 equal sides)

    You can't prove this, it is, generally, not true. By choosing D at different places along BC, angle EAD can take on many different values while the right side, not depending on D, is fixed. Was there some other condition on D you did not give?

    My bad, I forgot to add that AD splits the angle in 2 equal sides(angles).
