Which one of the following statements is true of parallel lines?
(a) Parallel lines never intersect with each other or meet at any point.
(b) Parallel lines have different slopes on a coordinate plane.
(c) Parallel lines are always straight lines.

Solution:

Two or more lines that lie in the same plane and never intersect or meet each other are known as parallel lines.

By definition of parallel lines

(a) Parallel lines never intersect with each other or meet at any point. So, this statement is true.

(b) Parallel lines have the same slope on a coordinate plane. So, this statement is false.

(c) Parallel lines need not be always straight. Curvy lines can be parallel too. So, this statement is false.

Thus, the only statement in option (a) is true about parallel lines.

Which one of the following statements is true of parallel lines?

Summary:

Option (a) Parallel lines never intersect with each other or meet at any point.
