Geometry

Question Analysis:
Applies the angle doubling rule to non-standard angle measurement.

Key Concept Explanation:
Rotation angle always twice the mirror angle
2 × 22.5° = 45°
Works for any angle, not just regular divisions

Step-by-Step Solution:
Measure angle between mirrors: 22.5°
Apply doubling rule: 2 × 22.5° = 45°
Direction depends on reflection order

Option Analysis:
A) Incorrect - Uses original angle
B) Correct - Properly doubled angle
C) Incorrect - Would require 45° mirrors
D) Incorrect - Over-rotation error
