In Geometry, a line is the longest between a line segment, a line and a ray. This is easy to determine given the definitions of each:
-A line, which is determined by any two points in it, extends infinitely in both of its ends.
-A line segment is the portion of a line contained between two points, including these points.
-Any point O of a line divides it into two parts called rays that have a starting point in O but are infinite on their other end.
So, a line segment is a segment with an end and a beginning, a ray has a beginning but not an end, and a line has no beginning or end, so a line is the longest.

What is a line segement?
A line segement is a line that starts at one point and ends at another. It has two endpoints.
How many points do you need to name a ray segement?
Just like line segments or lines, you just need two points to name them. Line ---.-----.-----------------.--------------> A B C D Line= AB Line= BC Ray= CD
Does a ray go on forever?
Yes, both a ray and a line go on forever, but unlike a line, and like a line segment, a ray has an endpoint.
What is the difference between a line segment and a ray?
a ray continues on and on but a line segment stops
What is a one dimensional and have infinite length?
a ray and a line
