Answer:
Δ ABC ≅ Δ XYZ by SAS criteria.
Step-by-step explanation:
Two triangles are there, one is Δ ABC and the other is Δ XYZ.
Now, given that AB = XY and BC = YZ.
Again it is given that ∠ ABC = ∠ XYZ
So, we can say that Δ ABC and Δ XYZ are congruent or Δ ABC ≅ Δ XYZ by Side-Angle-Side or SAS criteria.
So, it is not by the Side-Side-Side i.e. SSS criteria. (Answer)
