# Collinear Points

In basic geometry we learn about the points, line segments, lines , rays etc. These can be represented on a plane surface which we call it as two-dimensional surface. According to the basic definition, a plane surface contain infinite number of points. Also a line is made up of infinite number of points, which are called as collinear points. By the Euclidean property there exists one and only line passing through two given points. Therefore if we have three points in a plane, there will be two possibilities.

1. It is possible to draw three different lines passing through the three given points.

2. It is possible to draw one and only one line segment passing through the given three given points.

Is there any special name for these points? Yes they are called

**collinear points**. In this section let us see about the definition of collinear points and some examples on Collinear points.
