Answer: A. and are parallel.
C. and lie on the same plane.
E. and do not intersect.
Step-by-step explanation:
Given expression :
We know that '||' is the sign we use to show parallel lines.
It means and are parallel.
Also, parallel lines lie on the same plane.
So , and lie on the same plane.
It is known that the parallel lines are the lines which never intersect each other.
So and do not intersect.
Also, skew lines are lines which are not parallel.
But and are parallel.
So, and aare not skew.
