This is the picture

How can you prove that the two triangles are congruent? ASA SAS SSS AAS

OpenStudy (anonymous):

SAS?

OpenStudy (ddcamp):

Yes, good. Now, if we know that the two triangles are congruent, how can we prove that BD = DC?

OpenStudy (anonymous):

Im not sure, I can only figure out that AD bisects them...

OpenStudy (ddcamp):

"Corresponding Parts of Congruent Triangles are Congruent".

OpenStudy (ddcamp):

That would be step 5 in the proof.

AH okay thanks ^^ Mind helping me with a few others if it isn't too much trouble?
