If three points are collinear, then they lie on a line. Let first calculate distance between the 3 points i. Thus, P, Q and R all collinear. Davneet Singh has done his B.

As per the Euclidean geometry, a set of points are considered to be collinear, if they all lie in the same line, irrespective of whether they are far apart, close together, form a ray, a line, or a line segment. The term 'collinear' is derived from a Latin word where 'col' means 'together' and linear means 'line'. Thus, collinear, means the points lying together on a single line. Collinear points can be seen in our day-to-day lives, for example, the eggs placed in a row, or, the numbers printed on a ruler are collinear. As per the collinearity property, three or more than three points are said to be collinear when they all lie on a single line. The term collinearity has been used to indicate that the objects lie on a single line or in a row. Let us have a look at an example to understand collinearity better. If we plot these points in the cartesian plane, we find that they are collinear. When a line passes through three or more points, the points are said to be collinear points. In other words, the points lying on a straight line are called collinear points.

Show that the points are collinear

Collinear points are those points that lie on the same straight line. It is not necessary that they should be co-planar but they must lie on the same straight line. The word collinear is derived from the Latin words 'col' and 'linear' where 'col' stands for together and 'linear' means in the same line. The property of the points being collinear is known as collinearity. Let us learn more about collinear points in this article.
