What does CPCTC stand for?

• Corresponding Parts of Congruent Triangles are Congruent

• never use CPCTC it is not a thing

The Base Angles Theorem states:

• If two angles of a triangle are congruent, then the sides opposite of those angles are congruent.

• If two sides of a triangle are congruent, then the angles opposite of those sides are congruent.

• If two triangles are congruent, then their corresponding sides and angles are congruent.

• None of the above.
