True or false If two lines are coplanar then they must touch?
false
Can two lines be coplanar?
yes, two lines can be coplanar.
If two lines are not coplanar then they are neither intersecting nor parallel?
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
Do non coplanar lines intersect?
No. If two lines intersect, then they're definitely coplanar.
Are any two lines always coplanar?
No, not always. Skew lines are never coplanar, but parallel lines are.
True or false If two lines are coplanar then they must touch?
false
Can two lines be coplanar?
yes, two lines can be coplanar.
Two lines that have a point in common must be coplanar?
True
Two lines which intersect to form right angles?
...must be coplanar.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
If two lines are not coplanar then they are neither intersecting nor parallel?
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
What are two coplanar lines called that have no points in common?
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
Do non coplanar lines intersect?
No. If two lines intersect, then they're definitely coplanar.
Are any two lines always coplanar?
No, not always. Skew lines are never coplanar, but parallel lines are.
What are two coplanar lines that never intersect called?
Two coplanar lines that never intersect are called called parallel lines.
If two coplanar lines do not intersect then they must be what?
Skew. * * * * * FALSE. In fact, if they are skew, they must intersect. They have to be parallel for them not to intersect.
Are any two pairs of perpendicular lines coplanar?
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
