Triangle Congruence Postulates
SSS, SAS, ASA, AAS, HL
*included = in between
*non-included: not in between
** corresponding sides: sides that are in the same relative position (pay attention to angle markings to determine this)
Once you prove two triangles are congruent by one of the previous 5 postulates, you can use CPCTC to prove any other corresponding parts of those two triangles are congruent.
