You need four of them in order to construct a square.
Yes, I do understand the definition of a line segment. A line segment is a line that actually has two endpoints. Such endpoint is a triangle's or a square's side.
A line segment has one dimension . . . length.
Any line segment has infinitely many points and each one of them is specific to that line segment.
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 line segment has two end points.
Yes as for example the diagonals of a square
a musical line segment is a segment (paragraph) that you use to read put it also is music in many other forms
Draw a square. Find the midpoint of the bottom side and the left side, and also the middle of the square itself. Connect the midpoint of the bottom line with the middle of the square with a line segment. Connect the midpoint of the left side with the middle of the square with a line segment. Your second square uses part of the left and bottom side of the first square.
10 units.
A line segment has two endpoints
