Geometry

Question Analysis:
This question tests the fundamental difference between reflections over parallel versus intersecting lines.

Key Concept Explanation:
Parallel lines: Composition yields a translation (distance = twice the line separation)
Intersecting lines: Composition yields a rotation (angle = twice the angle between lines, centered at intersection)

Step-by-Step Solution:
Parallel case:
Reflect over line m, then line n (parallel to m)
Net effect: Translation perpendicular to lines, distance 2d (where d is separation)
Intersecting case:
Reflect over lines intersecting at angle θ
Net effect: Rotation by 2θ about intersection point

Option Analysis:
A) Incorrect: Reverses the correct relationship
B) Correct: Matches the theoretical distinction
C) Incor...
