Question Analysis:
This question checks your understanding of the formula for calculating the angle of rotation after two reflections.

Key Concept Explanation:
The resulting rotation after two reflections is twice the angle (smaller one) between the two lines of reflection.

Step-by-Step Solution:
If the lines intersect at an angle θ (smaller one), the resulting rotation is 2θ.

Option Analysis:
C is the correct answer because the resulting rotation is always double the angle (smaller one) between the reflection lines...
