In Euclidean geometry, if they are coplanar they must intersect. But if they are in different planes, they may not. The following example will illustrate this:
Picture yourself in a cuboid room - ie a normal shaped room. Stand with your back to one of the walls. Ray 1 forms the join of the wall behind you and the floor. Ray 2 is the line where the wall facing you meets one of the side walls. Rays 1 and 2 are not parallel but they can never meet - because they are not in the same plane.

What are coplanar lines rays or segments that do not intersect?
If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
How many times do parallel lines intersect?
parallel lines never intersect.
Would parallel lines intersect at a 90 degree angle?
no they are parallel therefore they will never intersect
Does parallel lines intersect at an angle of 90 degrees?
If lines intersect they CANNOT BE PARALLEL. Speak to your teacher!
What are lines that do not intersect called?
Lines that never intersect are parallel.
Do rays that are not parellel intersect?
Rays that are not parallel do not necessarily intersect. Rays have a starting point and if they diverge, they will not intersect. If they converge from their starting point, then they will eventually intersect.
Two collinear rays that do not intersect?
Two collinear rays that do not intersect are called parallel rays. This will only occur for a short time, however, because they will intersect at some point.
What two segments or rays in the Same plane are parallel?
Two lines of a plane are said to be parallel if they do not intersect and the perpendicular distance betweem them is always same.
What would it look like if you draw two rays that are not parallel to each other and will never intersect?
Parralel Lines.
Can parallel lines intersect?
No, never. Parallel lines are line that will NEVER intersect.
What are coplanar lines rays or segments that do not intersect?
If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
What parallel lines intersect?
Parallel lines in the Euclidean plane do not intersect but all parallel lines in the projective plane intersect at the point at infinity.
The point at which the rays of an angle intersect?
The point at which the rays of an angle intersect is the vertex.
Can a parallel lines intersect?
No they cannot.If they were to intersect they wouldn't be known as parallel lines.
Are lines that never intersect parallel or perpendicular?
parallel ============================================= Parallel. _____________________ _____________________ Those two lines will NEVER intersect.
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
How many times do parallel lines intersect?
parallel lines never intersect.
