Think you just answered your own question. A plane is a line. Two planes= two lines.
Two lines may or may not lie in the same plane, depending on their relationship. If the lines are parallel or intersecting, they exist in the same plane. However, if the lines are skew, meaning they do not intersect and are not parallel, they lie in different planes. Thus, whether two lines lie in the same plane is contingent on their geometric arrangement.
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.
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.
