What does CPCTC represent and
when would you use it?
CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent. It is a theorem in geometry that states that if two triangles are congruent, then their corresponding parts (sides and angles) are also congruent.
You would use CPCTC when you have two congruent triangles and need to prove that specific parts of the triangles are congruent, such as angles or sides. This can be helpful in proving properties of geometric figures or solving problems involving congruent triangles.
