We write line segment AB as (AB)  or (BA)  

Here, points A and B are the end points of the line segment.



A line extends in definitely in both directions.


A line as no end point.

We write line  AB  as (AB) 



Ray is a line with one end-point.


Here AB is a ray.

It can extend from point B, but point A is fixed.

We write it as (AB) 



(PQ) is a ray
