What does not have a point of intersection?
Two parallel lines, a plane and a line in a plane parallel to it.
Are two lines from the same plane parrellel?
They can be, but not necessarily. If two lines in the same plane never intersect, they are parallel. Though, two lines can exist in the same plane without being parallel. Ie, two lines that intersect at a 90 degree angle are perpendicular. Most lines in a plane aren't parallel.
Which in a two lines in a plane do not intersect?
Parallel lines
Two lines lie in one plane if and only if the lines are parallel?
Two lines are coplanar iff they are parallel OR intersect.
Two lines that do not intersect and are not in the same plane?
parallel lines :)
Two lines in the same plane that do not intersect?
They are parallel lines
What are two lines on the same plane that do not intersect?
Two lines that do not intersect on the same plane are Parallel lines.
If two lines do not intersect must they be parallel?
If the two lines lie in the same plane, and they do not intersect, then they are parallel. If they are not in the same plane, and do not intersect, then they are called skew lines.
If two parallel planes are cut by a third plane the lines of intersection are?
Parallel lines.
A and B do not intersect what information is needed to prove that they are parallel?
Pretty much the only thing you need to know to determine if two lines are parallel is the gradient of those lines. Simply put, are the lines on the same plane?
Are two lines that do not intersect skew?
Two lines that are not parallel and do not intersect are skew. If the non-intersecting lines are in the same plane then they are parallel.
Two lines in a plane that never intersect?
Parallel
Is any two lines lie in exactly one plane?
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
In a plane if two lines are perpendicular to the same line then they are parallel to each other?
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.
Two lines in the same plane that never meet?
Two coplanar (in the same plane) lines that don't meet are parallel.
If Two lines lie in one plane and do not intersect if and only if the two lines are parallel is this true?
Yes [in the Euclidean plane].
Two lines in the same plane that never intersect are called?
parallel lines
