Question

What additional information do you need to prove △ABC ≅ △DEF by the SSS Postulate?

A. BC = EF
B. AB = DE
C. AC = DF

Answer 1

the answer to this is C

Answer 2

The answer to this question is answer choice C.

For the SSS postulate, we need 3 pairs of congruent sides. However, in the image, there are only 2 pairs.

The missing pair in the image is AC and DF. If those are congruent, the triangle can be proven congruent by the SSS postulate.

Hope this helps! :)
