CPCTC Theorem

Corresponding Parts of Congruent Triangles are Congruent. Just five little words, yet they cause so much trouble and so many proofs! Well, get ready for the awesome as we apply this gem to SSS, SAS, ASA, AAS, and H-L.

CPCTC Proof Examples

Get ready for some major proof action as we learn how to use CPCTC as an additional step after more typical SSS, SAS, ASA, and H-L proofs.
