Given:
1 = 4
B = D

Prove:
AD = CB

Which of the following triangle congruence theorems would be used in this proof?

Step-by-step explanation:

<B and <D = angles

AD and BC = sides

<1 and <4 = angles

so on each side it has 1side and 2 angles, so the conclusion would be: that triangle is going to be ASA. Thank you for asking this question and I'll be happy to Obliged.
