the congruence theorems or postulates are: SAS AAS SSS ASA
The two triangle congruence theorems are the AAS(Angle-Angle-Side) and HL(Hypotenuse-Leg) congruence theorems. The AAS congruence theorem states that if two angles and a nonincluded side in one triangle are congruent to two angles and a nonincluded side in another triangle, the two triangles are congruent. In the HL congruence theorem, if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, the two triangles are congruent.

there are 4 types of congruence theorem-: ASA,SSS,RHS,SAS
SSS, SAS, ASA, AAS, RHS. SSA can prove congruence if the angle in question is obtuse (if it's 90 degrees, then it's exactly equivalent to RHS).
They are theorems that specify the conditions that must be met for two triangles to be congruent.

HA, LA, HL, LL [APEX]
It is a special case of ASA congruence.
The correct answer is the AAS theorem
