Question

What does CPCTC represent and when would you use it?

Answer 1

[AI-generated answer — Bot]

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent." It is a theorem used in geometry to prove that two triangles are congruent. It is used when two triangles have three pairs of corresponding sides and angles that are congruent.

Answer 2

Used to be called SSS, probably still is.

If corresponding sides of the two triangles are equal, then you don't
actually care about the angles.
