Work Step by Step

CPCTC is when corresponding parts of congruent triangles are congruent. For example, if Triangle ABC is congruent to Triangle DEF, then we would know that angle A would equal D, angle B would equal E, and C would equal F. This also applies to line segments. For example, segment AB would equal DE, and AC would equal DF. However, the parts must always be in the correct order to be congruent. DE could not be proven congruent to AC by CPCTC. So, I is the only one that would make sense in this question. Every other answer would require more information.
