Geometry

Question Analysis:
Check if diagonals are perpendicular.

Key Concept Explanation:
Perpendicular lines: slopes are negative reciprocals.

Step-by-Step Solution:
WY slope = (2−(−2))/(4−(−3)) = 4/7
XZ slope = (2−(−2))/(−1−2) = 4/(−3) = −4/3
Check: (4/7) × (−4/3) = (−16)/21 ≠ −1

Common Mistakes:
Assuming diagon...
