Question

Helppp !!
What is needed to prove ΔBCA≅ ΔEFD by AAS?

∠E ≅ ∠A ∠E ≅ ∠A

∠B≅∠ E

AB≅ DE

BC≅ FE

Answer 1

Isn't this the same question?

Answer 2

yeah but nothing would load

Answer 3

so i redid it

Answer 4

So, do you understand my explanation, or do you still need help?

Answer 5

i still need help

Answer 6

Then please say so.

Proof of congruence by AAS means to have two pairs congruent corresponding angles, and one pair of corresponding congruent sides.



More specifically, the congruent side is opposite (across from) one of the congruent angles. This is different from ASA where the congruent side is adjacent (next to) both congruent angles.

What are you still confused about?

Answer 7

so,... AB = DE ???

Answer 8

AB and DE are side lengths. You already have a pair of congruent angles and a pair of congruent sides (AS); to get AAS, you need another pair of congruent angles.
