The information that must be true to prove that both triangles are congruent by triangles congruent by the AAS theorem is: A. ∠B ≅ ∠E.
What is the AAS Congruence Theorem?
The AAS congruence theorem states that if two pairs of corresponding angles and a pair of non-included sides of two triangles are congruent, then both triangles are congruent triangles.
We are given the following:
- ∠A ≅ ∠D (one pair of congruent angles)
- AC ≅ DF (one pair of congruent)
What will make both triangles congruent by AAS theorem is: A. ∠B ≅ ∠E.
