Ab = xy, bc = yz, and angle b
is congruent to angle y,
mabc and axyz are congruent by
the sss criterion

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)

you are saying it as if a fact, not a question, but yes, you would be correct? ; )
