Collinear means that the points are on the same line.
Example Solution: E, H and G
Practice makes perfect
Collinear points are points that are all on the same line. You can always connect two points with a straight line, so it's the location of the third point that is crucial. Let's first arbitrarily pick two point and draw a line between them. Why not E and H?
To pick another point so that they are not collinear, we can pick any point on the cube except for J such as G.
