Geometry

Question Analysis:
The task is to identify parallel sides by calculating slopes.
The main focus is comparing slopes.

Key Concept Explanation:
Parallel lines have identical slopes.

Step-by-Step Solution:
WX slope = (1 − 1)/(6 − 2) = 0 (horizontal)
YZ slope = (4 − 4)/(1 − 5) = 0 (horizontal)
→ WX || YZ
XY slope = (4 − 1)/(5 − 6) = -3
WZ slope = (4 − 1)/(1 − 2) = -3
→ XY || WZ

Option Analysis:
A. WX ||...
