Geometry

Question Analysis:
This question focuses on identifying the composite transformation after two reflections.

Key Concept Explanation:
Two reflections over intersecting lines = Rotation about the intersection point.
Rotation angle = 2× angle between the lines = 2 × 45^∘ = 90^∘.

Step-by-Step Solution:
Lines intersect at 45^∘.
Net effect = Rotation of 90∘ about the intersection point.

Option Analysis:
A) Incorrect – Half the correct angle.
B) Correct – Matches 2 × 45^∘.
C) Incorrect – Requires parallel lines.
D) Incorrect – A glide reflection is a reflection...
