Which is a set of collinear points?

1. G, H, I
2. L, H, I
3. G, H, J
4. G, I, J

1. G, H, I

To determine the set of collinear points, we need to understand what "collinear" means.

Collinear points are points that lie on the same straight line. This means that if we were to draw a line connecting any two points in the set, it would pass through the third point.

Now, let's consider the given options:

1. G, H, I: We can draw a straight line passing through these points.

2. L, H, I: We cannot draw a straight line passing through these points.

3. G, H, J: We cannot draw a straight line passing through these points.

4. G, I, J: We cannot draw a straight line passing through these points.

Based on the definition of collinear points, we can conclude that option 1 (G, H, I) is the set of collinear points.

The set of collinear points is a set of points that lie on the same straight line.

Looking at the options given, the set of collinear points is 4. G, I, J.
