Final answer:
Two or more points that lie on the same line are referred to as 'collinear.' This is a common term used in geometry to describe the alignment of points on a single straight line.
Step-by-step explanation:
Two or more points are collinear if they lie on the same line. Therefore, the correct answer is 'c. collinear.' This term is used in geometry to refer to points that are located on a single straight line. If we imagine a line on a piece of paper, any points that touch that line without deviating from it are considered collinear.
To understand this concept further, let's consider three points. If you can draw a straight line through all three points without lifting your pencil, these points are collinear. On the other hand, points that do not lie on the same line are called non-collinear. So, if you cannot draw a straight line through all the given points at once, they are non-collinear.Two or more points are collinear if they lie on the same line. In other words, they can be connected by a straight line. For example, points A, B, and C are collinear if they all lie on the line AB, or points P and Q are collinear if they both lie on the line PQ.
