One line segment is 180 degrees because it is a straight line. If you have 2 or more intersecting line segments, the degree of the angle will vary.
A line segment has one dimension . . . length.
Probably three:The point is not on the segment nor the corresponding line,The point is in the line segment,The point is not in the line segment as given but would be if the segment were extended.
a musical line segment is a segment (paragraph) that you use to read put it also is music in many other forms
Draw a line segment with a straight edge.Place protractor on line segment with the center point on the end of the line and the line lined up with the bottom guide.Place a small dot on the 50o mark on the protractor.Place the straight edge on the end of the line segment and on the dot and connect the two.
A line segment has two endpoints
A line segment has exactly two endpoints. If it had less, then it would just be a point. If it was more, then it wouldn't be a segment anymore.
It's a flat line. Or a line segment. Or a "half line" with one endpoint (the vertex of the 0 degree angle).
Line segment AI, line segment BG, line segment GH and line segment CE
Just the two of them at each end of the line segment.
line segment, line ab, __ ab
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.
