1
Q
Segment
A
the part of a line consisting of two end points and all points between them
2
Q
Ray
A
the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint
3
Q
Opposite rays
A
two collinear rays with the same endpoint. Opposite rays always form a line
4
Q
Parallel lines
A
coplanar lines that do not intersect
5

A
noncoplanar lines therefore they do not intersect and they are not parallel
6
