Question

What else would need to be congruent to show that ABC PQR by SSS?

Answer 1

C. BC is congruent with QR is your answer

you want to make sure ALL sides are congruent to have SSS

hope this helps

Answer 2

Answer: C. $\overline{BC}=\overline{QR}$

Step-by-step explanation:

In the given figure we have two triangles  ΔABC and ΔPQR

Given: $\overline{AC}=\overline{PR}$

$\overline{AB}=\overline{PQ}$

SSS postulate of congruence says that if  three sides of a triangle are congruent or equal to corresponding three sides of other triangle then the triangles must be congruent.

Therefore, we need $\overline{BC}=\overline{QR}$ to show that ΔABC  and ΔPQR are congruent by SSS postulate of congruence.
