- AAB = DE
- BBC = DF
- CBC = EF
- DAC = DF
Step-by-Step Solution
ASA needs the side between the two angles: AB (between ∠A and ∠B) and DE (between ∠D and ∠E). BC = EF or AC = DF would be AAS; BC = DF does not correspond.
Answer: A) AB = DE
You know ∠A = ∠D and ∠B = ∠E. Which side equality gives congruence by ASA (not AAS)?
