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.
What else can I help you with?
Two lines that on the same plane that never intersect?
parallel lines If they are not on the same plane and never intersect they are skew
Two lines that do not intersect and are not in the same plane?
parallel lines :)
Do skew lines intersect if they are in the same plane?
No, skew lines cannot be in the same plane, since they do not have a point on common. Two lines intersect if they lie in a common plane, and by definition, these intersecting lines are not skew lines.
If two lines lie in the same plane and do not intersect then they are?
Parallel Lines.
What are the two lines in the same plane that never intersect?
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.
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 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.
What is two lines that lie on the same plane and don't intersect?
Two parallel lines. Such lines have the same slope.
Two lines that on the same plane that never intersect?
parallel lines If they are not on the same plane and never intersect they are skew
Two lines that do not intersect and are not in the same plane?
parallel lines :)
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.
How many parrellel lines are there in a nonagon?
In a regular nonagon no two sides are parallel.
Two lines that lay in the same plane are?
coplanar (which means that they lie on the same plane)
Do skew lines intersect if they are in the same plane?
No, skew lines cannot be in the same plane, since they do not have a point on common. Two lines intersect if they lie in a common plane, and by definition, these intersecting lines are not skew lines.
What are two lines that do not lie in the same plane and do not intersect?
skew lines
If two lines lie in the same plane and do not intersect then they are?
Parallel Lines.
