Question

What is the measure of a whole angle?

• A. $60^\circ$
• B. $45^\circ$
• C. $180^\circ$
• D. $360^\circ$

Hint:

A whole angle means one complete rotation, which equals $360^\circ$.

Answer 1

The Correct Option is D

Step 1: Understanding angle types
Angles are categorized based on their measurement in degrees:
- Acute angle $<$ 90°
- Right angle = 90°
- Obtuse angle $>$ 90° but $<$ 180°
- Straight angle = 180°
- Reflex angle $>$ 180° but $<$ 360°
- Whole angle = full turn

Step 2: What is a whole angle?
A whole angle is one complete rotation starting from a ray, making a full circle and coming back to its initial position.
This forms a complete revolution and is measured as:
Whole angle = $360^\circ$
\[ \boxed{\text{Correct Answer: (D) } 360^\circ} \]
