1.4 segments, rays, parallel lines and planes Flashcards
1
Q
segment
A
the part of a line consisting of two endpoints 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 intercect
5
Q
skew lines
A
are noncoplanar; therefore, they are not parallel and do not intersect.
6
Q
parallel planes
A
are planes that do not intercect.
