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

The answer is d. this is because the given already gives us a congruent angle and side measurement. a and b show the congruencey of angles which is not what we are looking for so it's down to c and d. the reason d would be a better choice than c is because we want to go in order with the original order the points of the triangle are shown. that being abc to xyz and the closest thing to that would be bc to yz.note: sas means 'side-angle-side'(hopes this makes sense i'm terrible at explaining things)
