Proving Triangle Congruent SSS SAS CPCTC

These two triangles are congruent. If ∠C is 40^o find the measure of ∠F.

• 40^o

When does one use CPCTC?

• Before triangles are congruent

• After triangles are congruent

• Whenever one wants, there are no restrictions

• There is no such thing as CPCTC
