Worked Solution
Step 1: Recall that a right angle is exactly 90°.
Step 2: An angle greater than a right angle is any angle larger than 90°.
Step 3: Check each option:
- 120° > 90° ✓ (greater than a right angle)
- 90° = 90° ✗ (this IS a right angle, not greater)
- 45° < 90° ✗ (smaller than a right angle)
- 30° < 90° ✗ (smaller than a right angle)
Answer: An angle of 120°
Correct answer: An angle of 120°
