Which of the following are models for perpendicular lines :
The letter V.

Answer

To determine if the letter V is a model for perpendicular lines, we need to understand what perpendicular lines are. Perpendicular lines are lines that intersect at a right angle (90 degrees).

### Step-by-Step Solution:

1. **Understanding Perpendicular Lines**:
- Perpendicular lines intersect at a right angle (90 degrees).
- Visualize two lines crossing each other to form four angles. If any of those angles is 90 degrees, the lines are perpendicular.

2. **Analyzing the Letter V**:
- The letter V consists of two straight lines that meet at a point.
- When you look at the letter V, the two lines form an angle at the bottom.

3. **Measuring the Angle**:
- The angle formed by the two lines of the letter V is not a right angle. Instead, it is an acute angle (less than 90 degrees).
- Therefore, the lines do not intersect at a right angle.

4. **Conclusion**:
- Since the angle formed by the lines of the letter V is acute, it does not represent perpendicular lines.
- Thus, the letter V is **not** a model for perpendicular lines.

### Final Answer:
The letter V is not a model for perpendicular lines.
