B. AC = DF
C. BC = EF

What additional information do you need to prove ABC DEF by the SSS Postulate A AB DE B AC DF C BC EF class=

Respuesta :

The answer to this question is answer choice A.

We want three pairs of congruent sides, but we only have 2 pairs in the image. If AB is congruent to DE, we'll have 3 pairs of congruent sides and the triangle will be proven congruent by the SSS postulate.

Hope this helps! :)
