CPCTC: Corresponding Parts of Congruent Triangles are Congruent You will use this during your proofs.

6. You cannot use CPCTC to prove 2 triangles are congruent
**You cannot use CPCTC to prove 2 triangles are congruent. ** You cannot use CPCTC BEFORE one of the 5 congruence postulates (SSS, SAS, etc.) **CPCTC can only be used AFTER two triangles have been proved congruent!!!
