skew lines
Parallel lines would always lie in the same plane. They would need to be skew lines.
One if the two lines meet, none otherwise. But skew lines do not lie in the same plane, by definition.
They're either parallel lines or skew lines.
There is no specific term but you could try "non-coplanar".
If they are straight lines, then they define a plane in which both lines lie.
the answer would have to be skew
true * * * * * No, false. Any two straight lines that intersect define a plane in which both those lines lie.
No because they lie on the same line
Not necessarily. Points may lie in different planes.
skew lines
skew lines
Skew lines.
Intersecting lines are those that lie in the same plane and cross each other at some point. Unless they are parallel, lines in the same plane always cross.
Parallel lines would always lie in the same plane. They would need to be skew lines.
C.intersecting lines
One if the two lines meet, none otherwise. But skew lines do not lie in the same plane, by definition.
