Yes it can
In geometry, yes, those are different names of the same line segment.
No its not the same
Congruent line segment
Yes, while naming a line segment, as long as the two points are on the line, it does not matter what order they are in or which points they are. well their not
The step that ensures the new line segment has the same length as the original line segment involves using a compass to measure the distance between the endpoints of the original segment. By placing the compass point on one endpoint and adjusting it to the other endpoint, the same width can be transferred to the new location where the new segment will be constructed. This guarantees that the new line segment will be congruent in length to the original one.
They are not. A line segment is of finite length whereas a ray is infinitely long.
NO, but they can intercpet in a line which is not the same as a segment of course.
Collinear lines lie on the same straight line.
Yes. Because both "MN and "NM" are endpoints.
The two phrases are equivalent: collinear means in the same line [segment].
no they form a line segment
According to the symmetric property (and common sense) line segmetn AB is congruet to line segment BA since they are the same segment, just with a different name
