What else would you need to be congruent to show that abc =xyz by sas

Option (c) is correct.

In addition to given congruence we need to show

Step-by-step explanation:

Given: Given two triangles ΔABC and ΔXYZ and and  

We have to find what else we need to show to prove two triangles similar that is ΔABC ≅ ΔXYZ by SAS similarity.

SAS Similarity criterion states that for given two triangle if two sides and angle between those two sides are congruent,then two triangles are said to be similar.

Thus, for given triangles, ∠A lies in between BA and AC and ∠X lies in between XY and XZ.

So in addition to given congruence we need to show

Thus, option (c) is correct.
