Answer:
AAA and SSA are not real theorems
Step-by-step explanation:
Side Side Angle is not a valid theorem because the unknown side could be located in two different places which would not prove the triangles congruent.
Angle Angle Angle is also not a valid theorem because all the angles might have congruent measures but that doesn't mean the sides will have the same measures therefore AAA cannot prove triangles congruent.
The rest are valid congruence theorems.
