HERE IS SOME INFORMATION ON THE CPCTC PROOF OF CONGRUENT TRIANGLES
Corresponding parts of congruent triangles are congruent
CPCTC
is a short hand acronym for the phrase
'corresponding parts of congruent triangles are congruent' What does CPCTC mean? It means that once we know that two triangles are congruent, we know that all corresponding sides and angles are congruent!

How to prove triangles are congruent with SSS, SAS, AAS, and other postulates
Remember the meaning of congruent triangles. Two triangles are congruent if all 3 sides and 3 angles of one triangle equal all 3 sides and all 3 angles of the other triangle. CPCTC takes advantage of this fact. The general method is to first prove that 2 triangles are congruent and then use that knowledge to prove that a certain pair of corresponding sides or angles are congruent
