a. AB←→ and CD←→ do not intersect.

b. AB←→ and CD←→ intersect at 90° angles.

c. The perpendicular distance between AB←→ and CD←→ increases as the lines are traversed left to right.

d. The perpendicular distance between AB←→ and CD←→ decreases as the lines are traversed right to left.

Answer 1

What is the definition of parallel lines?

Answer 2

when two lines don't meet

Answer 3

thank you cx

Answer 4

Parallel lines are two lines that lie in the same plane and do not intersect.
(In the definition of parallel lines, you must include the part about the lines being in the same plane because if not the lines may never meet but also not be parallel.)

Answer 5

You're welcome.
