Prove that any triangle that has two equal angle bisectors is actually isosceles. How can I prove this.I have attempted with the Sine Rule for this purpose.[For help you may visit http://www.mathsisfun.com/algebra/trig-sine-law.html]

well if angle bisectors are equal then twice those bisectors will alos be equal,

this solves the problem

two eaul angles gives a isosceles traingle!!!

All right,twice the angle bisectors are equal to each other,but how does that solve the problem?Please explain it.
