Answer:
The answer is: CPCTC.
Explanation:
CPCTC is an acronym for the corresponding parts of congruent triangles to be congruent.
CPCTC is commonly used at or near the end of a test that asks the student to show that two angles or two sides are congruent. It means that once two triangles are shown to be congruent, the three pairs of corresponding sides must be congruent and the three pairs of corresponding angles must be congruent.
