When can I use CPCTC?
You can use it to corresponding parts of a trianglr
How can you use SSS with CPCTC?
You can prove that to triangles are congruent with SSS, then use CPCTC to prove that two corresponding angles of those triangles are congruent.
If lmn xyz which congruences are true by cpctc?
If lmn xyz which congruences are true by cpctc: ml=yx ln=yz y=m
What needs to happen before you can use the reason CPCTC in a geometric proof?
Before using Corresponding Parts of a Congruent Triangle are Congruent theorem (CPCTC) in a geometric proof, you must first prove that there is a congruent triangles. This method can be used for proving polygons and geometrical triangles.
