Proof with an isosceles triangle

[Trilla]

I honestly do not know where to start on this problem.
Prove that in an isosceles triangle, the angle bisectors that pass through the base angles are congruent. State the coverse of this statement.

Have you studied geometry or proofs at all? If not, then there is way too much missing information for us to help. If so, then I'll assume that the above is an exaggeration. In hopes of the latter...

Prove that in an isosceles triangle, the angle bisectors that pass through the base angles are congruent. State the coverse of this statement.

Draw the picture. What theorems or definitions do you have about isosceles triangles? What theorems or definitions do you have about angle bisectors? Have you tried proving anything about congruence of the triangles formed inside the original triangle, when you drew the bisectors?

Please be complete. Thank you!
