## KrystaRenee Someone mind helping me with this proof? Given: <A is congruent to <C BD bisects <ABC Prove: D is the midpoint of AC Statements BD bisects <? <ABD is congruent to <CBD <A is congruent to <C BD is congruent to ? △ABD is congruent to △CBD AD is congruent to ? D is the midpoint of AC Reasons Given Definition of ? bisector ? Reflexive property ? postulate Corresponding parts of congruent △s are congruent Definition of ? one year ago one year ago

did u try this ?

3. KrystaRenee

Yeah. I've got most of the answers. I just don't know if I'm right on a few.

BD bisects <ABC. BD is congruent to BD. AD is congruent to CD. Definition of angle bisector. Idk what that random question mark is. AAS or SAA postulate. And definition of midpoint?

6. Hero

There's no such thing as SAA posulate

7. Hero

By the way <A congruent to <C is also given

8. Hero

That solves the mystery of the "random question mark"
