with no other details I can only explain it as the distance between point R and point A. More details are needed if you want that distance when compared with other points.
Line segment AI, line segment BG, line segment GH and line segment CE
line segment
A line extends forever into space and a line segment is a segment or part of a line, so a line is longer than a line segment.
a line can be indefinitely extended but a line segment is a part. a line segment cannot be extended:)
A line segment has two end points. This is called an line segment.
if it's between line segment or line, would it be line segment? i think line segment is the answer
A line segment.A line segment.A line segment.A line segment.
Bisect a segment is to divide the line segment into 2
a line segment has no area. By definition a line segment is a part of a line, thus it has no area
Line Segment
A line segment has end points
In geometry a line is thought of as extending infinitely in both directions. A line segment is part of a line.
