Given: line AB is congruent to line AC, Angle BAD is congruent to angle CAD.

Prove: line AD bisects BC

Picture: An upside down triangle divided inhalf to form two triangles Angle BAD and angle CAD. They share a common side of AD. and point D bisects line BC. and Angle c and Angle B are corresponding and congruent.

what i have so far

given info

Line DA is congruent to Line DA by Reflexive Prop or EQuality

angle C is congruent to angle B by the Corresponding parts of congruent triangles are congruen. CPCTC.

but i do not know where to go from that..

As far as I can tell, it doesn't matter which lines are congruent.

<BAD and <CAD are adjacent angles which are equal.

Therefore they bisect <CAB

Gussy it up, but that's the crux of the argument.
