The measure of a reflex angle is than `180^@` and than `360^@`.

Options

A. Smaller, greater
B. Smaller, smaller
C. Greater, smaller
D. Greater, greater

Answer

To solve the question regarding the measure of a reflex angle, we need to understand the definitions of angles, specifically reflex angles.

### Step-by-Step Solution:

1. **Understanding Reflex Angles**:
- A reflex angle is defined as an angle that measures more than 180 degrees but less than 360 degrees.

2. **Identifying the Range**:
- Since a full circle is 360 degrees, any angle that is more than 180 degrees but less than 360 degrees qualifies as a reflex angle.

3. **Setting Up the Inequalities**:
- From the definition, we can set up the inequalities:
- Reflex angle > 180 degrees
- Reflex angle < 360 degrees

4. **Choosing the Correct Options**:
- Based on the inequalities, we can conclude that the measure of a reflex angle is:
- Greater than 180 degrees
- Less than 360 degrees

5. **Final Answer**:
- Therefore, the correct options to fill in the blanks are:
- Greater than 180 degrees
- Less than 360 degrees

### Summary of the Answer:
The measure of a reflex angle is **greater than 180 degrees** and **less than 360 degrees**.
