SSA
We can immediately exclude AAS and ASA because to fit those criteria, two angles have to be congruent to begin with. SAS will also ensure that two angles are congruent because the two sides are opposite to the two angles that you know nothing about, and by the law of sines assure you know their proportion. Knowing A/B, C, and A+B+C (which is always 180 degrees) gives you enough information to uniquely determine the remaining angles, thereby ensuring congruence. Thus the only option given that doesn't ensure that two angles are congruent is SSA.
