Question

What additional congruence do you need in order to prove that triangleABE c triangleDBC by the ASA congruence postulate? What additional congruence do you need in order to prove that triangleABE c triangleDBC by the ASA congruence postulate? @Geometry

Answer 1

Here is a pic

Answer 2

Well, angle ABE and angle CBD are congruent by the Vertical Angles Theorem.


So, if we find that angle A and angle D are congruent, we can prove triangle ABE and DBC are congruent by the ASA Congruence Postulate. Does that make sense?

Answer 3

You do know that this was a year ago right o.o

Answer 4

Yeah, I know :D It might help someone else that has the same problem out :D

Answer 5

Oh yeah i guess you're right :P
