I'm not sure if you're missing a "NOT" in the question, or the wording is wrong, but three of these are theorems or postulates used to prove triangles congruent, while one is not.
Angle-side-angle (ASA) is used when two angles and an included side are congruent, side-side-side (SSS) is used when all three sides are congruent, and side-angle-side (SAS) is used when two sides and an included angle are congruent. All these are theorems or postulates used to prove triangles congruent.
Angle-angle-angle (AAA), however, is not.
