Question Analysis:
This question asks about recognizing rotational equivalence.
The main focus is understanding angle direction equivalence in rotation.

Key Concept Explanation:
Rotating:
90° clockwise = 270° counterclockwise
180° clockwise = 180° counterclockwise
270° clockwise = 90° counterclockwise
This is because a full circle is 360°, and: 360° − 90° = 270°

Step-by-Step Solution:
Start with 90° clockwise.
To find the equivalent counterclockwise angle: 360° – 90° = 270°
So: 90° clockwise = 270° counterclockwise
✅ Correct answer: D

Option Analysis:
A. ❌ 270° clockwise = 90° counterclockwise
B. ❌ 90° c...
