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.

A ray is different from a segement because a ray is half of a line and does not end in one side only but the segement it is half of a line that ends.

A line segement is a line that starts at one point and ends at another. It has two endpoints.

Just like line segments or lines, you just need two points to name them. Line ---.-----.-----------------.--------------&gt; A B C D Line= AB Line= BC Ray= CD

A line that has a starting point and an end point.
