1.4: segments rays paralell 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 points of the line on one side of the endpoint
3
Q
opposite rays
A
to collinear rays with the same endpoint opposite rays always form an endpoint
4
Q
parallel lines
A
coplanar lines that do not intersect
5
Q
skew lines
A
noncoplanar lines they are not parallel and do not intersect
6
Q
parallel planes
A
planes that do not intersect a line and plane that do not intersect are also parallel
