Line A is skew to Line B, when line A does not intersect line B and also they are not in the same plane.
None of them
there are infinitely many segments in a line.
That is a line segment that is "skewed up". It doesn't work right. It gets tossed in the heap that becomes other / lesser polygons and such and may even become a dreaded "circle".
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
Line A is skew to Line B, when line A does not intersect line B and also they are not in the same plane.
They can be, and are, "skew". If they are not lines, they cannot be "skew lines".
segments that are notcoplanar. (not in the same plane)
None of them
One pair of opposite sides: they may be top and bottom or two sides, or they could both be skew.
A line and a plane that do not intersect are always skew. Skew refers to two or more lines or planes that are not parallel and do not intersect. Since a line and a plane are different-dimensional objects, they will never intersect and will always be skew.
Answer is a skew lines do not lie in the same place
They can not be line segments on the same line, but they can both be line segments.
Sometimes.
That's true.
They could be if they are both skew to the same line.
They are skew line. Skew line are two lines that do not intersect but are not parallel.Another definition is skew lines are straight lines that are not in the same plane and do not intersect.Either way, skew lines are the answer to your question since they are noncoplanar and do not intersect.
