Classify the angles whose magnitudes are given below.
`50^(@)`
`92^(@)`
`185^(@)`
`90^(@)`
`180^(@)`

Answer

To classify the angles given in the question, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Angle Types**:
- **Acute Angle**: An angle that measures less than 90 degrees.
- **Right Angle**: An angle that measures exactly 90 degrees.
- **Obtuse Angle**: An angle that measures more than 90 degrees but less than 180 degrees.
- **Straight Angle**: An angle that measures exactly 180 degrees.
- **Reflex Angle**: An angle that measures more than 180 degrees.

2. **Classify Each Angle**:
- **50 degrees**: Since 50 is less than 90, it is classified as an **Acute Angle**.
- **92 degrees**: Since 92 is greater than 90 but less than 180, it is classified as an **Obtuse Angle**.
- **185 degrees**: Since 185 is greater than 180, it is classified as a **Reflex Angle**.
- **90 degrees**: Since 90 is exactly 90, it is classified as a **Right Angle**.
- **180 degrees**: Since 180 is exactly 180, it is classified as a **Straight Angle**.

### Final Classification:
- **50 degrees**: Acute Angle
- **92 degrees**: Obtuse Angle
- **185 degrees**: Reflex Angle
- **90 degrees**: Right Angle
- **180 degrees**: Straight Angle
