For the answer to the question above asking <span>What additional information would you need to prove that ΔABC ≅ ΔDEF by SSS? The answer to your question is </span><span>AB = DE & BC = EF, so the only sides missing are AC = DF, </span>
<span>so Side AC is congruent to side DF is the answer.
I hope my answer helped you. Have a nice day! </span>
