What does CPCTC stand for?
Corresponding Parts of Congruent Triangles are Congruent
Ok..but what does that mean?
Prove KJ $$ \cong $$ JI
Prove ML $$ \cong $$ MN
The proof below uses CPCTC to prove that the diagonals of a rhombus bisect the shape's angles. This proof relies upon CPCTC.
All that is necessary for this proof is the following definition for a rhombus: a parallelogram with four congruent sides.
