Find the minimum number of points at which three lines intersect.

Options

A. 1
B. 3
C. 2
D. 0

Answer

To find the minimum number of points at which three lines can intersect, we can follow these steps:

### Step 1: Understand the Concept of Intersection
When we talk about lines intersecting, we are referring to the points at which two or more lines meet. For three lines, we want to determine how they can intersect with each other.

### Step 2: Consider the Arrangement of Lines
To minimize the number of intersection points, we can arrange the three lines in such a way that they all meet at a single point. This means that instead of each line intersecting with every other line at different points, they all converge at one location.

### Step 3: Visualize the Lines
Imagine drawing three lines on a piece of paper. If you draw them so that they all cross at the same point, you will see that there is only one intersection point.

### Step 4: Conclusion
Thus, the minimum number of points at which three lines can intersect is 1. This occurs when all three lines intersect at the same point.

### Final Answer
The minimum number of points at which three lines intersect is **1**.
