How many degress are there in:
a straight angle

Answer

To find out how many degrees are in a straight angle, follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Straight Angle**:
A straight angle is formed when two rays originate from the same point and extend in opposite directions, creating a straight line.

2. **Visualize the Straight Angle**:
Imagine a straight line. If you were to measure the angle formed by the two rays that make up this line, you would see that they create a straight angle.

3. **Measure the Angle**:
By definition, a straight angle measures 180 degrees. This is because a full rotation around a point is 360 degrees, and half of that rotation (which forms a straight line) is 180 degrees.

4. **Conclusion**:
Therefore, the measure of a straight angle is 180 degrees.

### Final Answer:
A straight angle has **180 degrees**.
