Question

What additional information is needed to show that ABC = DEF by SSS?

Answer 1

D.) AC ≈ DF

Explanation:

The SSS (Side-Side-Side) congruence postulate states that 2 triangles will be congruent assuming that all 3 of their sides are congruent.

In this case, we know that:

1. AB ≈ DE
2. CB ≈ FE

So, that's two pairs of congruent sides. We need one more pair of congruent sides to prove SSS congruence. The last two remaining are sides CA and FD!
