Question

What else would need to be congruent to show that ABC XYZ by ASA?

Answer 1

Answer: C, Y, B

Step-by-step explanation:

Answer 2

Answer: Choice C. Angle Y = Angle B

==========================================================

Step-by-step explanation:

ASA stands for "angle side angle".

To use ASA, we must have two pairs of congruent angles, as well as a pair of congruent sides. The sides must be between the angles in question.

So far we're given

• Angle Z = Angle C
• CB = ZY

The thing we're missing is the other pair of congruent angles. So the missing congruent pair of angles is Angle Y = Angle B as those two angles are adjacent to the segments mentioned above.

Something like angle A is not adjacent or touching segment CB. Also, angle X is not adjacent to segment ZY. So we can rule these angles out. We'd only use these angles if we were dealing with AAS instead of ASA.
