The five congruency theorems for triangles are:
- Side-Side-Side (SSS) Theorem: If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
- Side-Angle-Side (SAS) Theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
- Angle-Side-Angle (ASA) Theorem: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.
- Angle-Angle-Side (AAS) Theorem: If two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.
- Hypotenuse-Leg (HL) Theorem: In right triangles, if the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle, the triangles are congruent.

What are the congruence theorems or postulates?
They are theorems that specify the conditions that must be met for two triangles to be congruent.
What are some different triangles?
You have acute, right, and obtuse triangles when referring to the measure of the largest angle, and you have equilateral, isosceles, and scalene triangles when referring to the congruency of the triangle's sides.
Congruence theorems for right triangles?

Why corresponding parts AAA triplet does not prove congruency?
Because triangles add up to 180 degrees
Which postulate theorem verifies the congruence of two right triangles?
RHS congruency, or, right angle, hypotenuse and corresponding side.
What are the five triangle congruency theorems?
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).
