Question

I need help with 3 geometry questions!

Answer 1

Triangle ABC is congruent to triangle DEF. In triangle ABC, side AB measures 9, side BC measures 3x+1, and side CA measures 7. In triangle DEF, side DE measures 9, side EF measures 2x+2, and side FD measures 7. What equation would help you to solve for the side length of BC and EF? Explain your reasoning using complete sentences.

Answer 4

Triangle ABC is congruent to triangle DEF
the order of the letters mean this:
you "match up" point A with point D, B with E and C with F

in other words, side AB matches up with side DE
for your question notice side BC matches up with side EF
