Prove that the tangents drawn at the ends of a diameter of a circle are parallel.

Explanation

To prove that the tangents drawn at the ends of a diameter of a circle are parallel, we can follow these steps:

### Step-by-Step Solution:

1. **Draw the Circle and Diameter**:
- Let \( O \) be the center of the circle. Draw a circle with center \( O \) and a diameter \( AB \) passing through \( O \).

**Hint**: Visualize the circle and label the center and the endpoints of the diameter.
