Answer:
Explanation:
The first one is not provable using any postulate.
You are given 2 sides that are equal. You have an angle that is congruent to another angle that is vertically opposite the first angle.
So you have SA. But the third side is not given nor can it be derived. So that is the odd pair out.
The second set (middle) are proved to be congruent by SAS.
The last set (right) show congruency using SSS.
