simple geometry fact that I dont understand...URGENT

the question is what constitutes a collinear?

Also why dont we have a glossary in math?

Hi Alberto,

Three or more points are said to be collinear if they all lie on the same straight line. Some more info about collinear points can be found here.

Hope this helps! Let me know if you have any further questions!
