What is CPCTC?

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.Here are some examples that I hope can help you throughExample 1:Let's say that Triangle ABC has these measures:Let's also say that Triangle DEF has the measures:Then you know that angle C is congruent to angle F through CPCTC.Example 2:Let's say that Triangle ABC has these measures:Let's also say that Triangle DEF has the measures:Then you know that side CA is congruent to side FD through CPCTC.Example 3:Let's say that Triangle ABC has these measures:Let's also say that Triangle DEF has these measures:Then you know that side AC is congruent to DF through CPCTC.You also know that angle C is congruent to angle F through CPCTC.You also know that angle A is congruent to angle D through CPCTC.
