What do you mean by collinear points ?
How many lines can you draw passing through three collinear points ?
Given three collinear points A,B and C . How many line segments do they determine ? Name them.

Answer

### Step-by-Step Solution:

1. **Definition of Collinear Points**:
- Collinear points are defined as three or more points that lie on the same straight line. For example, if we have points A, B, and C, and they all lie on the same line, then they are considered collinear.

2. **Number of Lines Through Collinear Points**:
- When we have three collinear points (like A, B, and C), we can draw only one straight line that passes through all three points. This is because collinear points are defined by their alignment on a single line.

3. **Line Segments Determined by Collinear Points**:
- Given three collinear points A, B, and C, we can determine the following line segments:
- Line segment AB (between points A and B)
- Line segment BC (between points B and C)
- Line segment AC (between points A and C)
- Therefore, three line segments are formed by these points.

### Summary of Answers:
- **Definition of Collinear Points**: Three or more points that lie on the same straight line.
- **Number of Lines Through Three Collinear Points**: Only one line can be drawn.
- **Line Segments Determined by Points A, B, and C**: Three line segments: AB, BC, and AC.
