Question

select the most precise and correct definition of parallel lines from among those that are given.
choose 1 answer
(a) two distinct lines are parallel if one can be rotated to sit on top of the other.
(b) two distinct lines are parallel if they point in the same direction.
(c) two distinct lines are parallel if they are in the same plane and never intersect each other.

Explanation:

Parallel lines in a plane are defined as lines that do not intersect. Option A's translation - based definition is not the most precise. Option B's "point in the same direction" is a bit vague without the plane - context. Option C gives the standard geometric definition of parallel lines in a plane.

Answer:

C. Two distinct lines are parallel if they are in the same plane and never intersect each other.
