What are the names of points A and B of segment AB? Think about whether it can be argued that segment AB and segment BA are one and the same segment. Does the straight line have ends? And the beginning? Is it true that line AB and line BA are one and the same line?

Points A and B of segment AB are called the beginning and end of the segment.
It can be argued that the segment AB and the segment BA are one and the same segment, since the names of the segments are read in any order. Also, a segment can have a direction, respectively, the beginning of a direction can begin both at point A and at point B. Therefore, a directed segment can be called both BA and AB.
The straight line has no beginning or end. The beginning and the end have only a segment. Only the beginning has a ray.
