If the line 1 passing through the points A and B also passes through the point C, then what are the three points A, B and C called?

Answer

To solve the question, we need to understand the relationship between the points A, B, and C in relation to the line that passes through them.

**Step-by-Step Solution:**

1. **Identify the Points**: We have three points, A, B, and C.

2. **Understand the Line**: The problem states that there is a line (let's call it line 1) that passes through points A and B.

3. **Include Point C**: It is also mentioned that line 1 passes through point C. This means that point C lies on the same line as points A and B.

4. **Definition of Collinear Points**: When three or more points lie on the same straight line, they are referred to as "collinear points."

5. **Conclusion**: Therefore, since points A, B, and C all lie on line 1, we can conclude that points A, B, and C are called collinear points.

**Final Answer**: The three points A, B, and C are called collinear points.
