Asap! will give ! only need two reasons! supply the reasons missing from the proof below given: line ab is congruent to line ac, angle bad is congruent to angle cad prove: line ad bisects line bc

Prove

Line AD bisects line BC.

Now, the missins reasons are numeral 4 and 5.

4.           4. By SAS postulate.

SAS postulate states if two triangles has two pairs of corresponding sides congruent and the pair of corresponding angles between them are also congruent, then those triangles are completely congruent.

5.       5. By congruence of corresponding sides.

After we prove a congruence, we can make several congruent deductions of the rest of elements between those congruent triangle. In this case, we deduct that BD and CD are congruent because those triangles are congruent.

answer: i dont know but if you try hard you will get it right : )
