Triangle ABC is congruent to triangle DEF. In triangle ABC, side AB measures 13, side BC measures x+13, and side CA measures 16. In triangle DEF, side DE measures 13, side EF measures 3x−20, and side FD measures 16. What equation would help you to solve for the side length of BC and EF? Explain your reasoning using complete sentences.

this is what I work ( CAN YOU HELP ME ADD MORE) : Since AB and DE is 13, and CA and FD is 16, that means both BC and EF are congruent which is given. corresponding parts of congruent triangles are congruent (CPCTC).
