Geometry

Question Analysis:
This tests understanding of AAS requirements when multiple parts are possible.
The main focus is on:
Choosing the correct non-included side
Eliminating redundant information

Key Concept Explanation:
Needed: Side opposite one given angle
XZ is opposite ∠Y → proper non-included side

Step-by-Step Solution:
Already given two angle pairs
For AAS, need side opposite either ∠Y or ∠Z
XZ is opposite ∠Y → matches UW

Option Analysis:
(A) Included side → would make ASA
(B) Correct non-included si...
