Step 1: Understanding the Measure of a Whole Angle.
A full angle (also called a complete angle) measures 360°, which is the total rotation around a point. It represents a full circle.
Step 2: Verifying the Options.
- Option (1): 60° is the measure of a smaller angle, not a whole angle.
- Option (2): 45° is also a smaller angle.
- Option (3): 360° is the measure of a complete angle, which is the correct answer.
- Option (4): 90° is a right angle, not a whole angle.
Conclusion:
Therefore, the correct answer is (3) 360°.
