Answer:
True
Step-by-step explanation:
Lines in three dimensions can be one of ...
Lines are coplanar when a plane can be defined that includes the entirety of both of them. In the attached image, lines m₁ and n intersect and both lie in the gray plane. They are coplanar.
Lines m and m₁ are parallel, and both are contained in the turquoise plane. They are coplanar. A plane can always be drawn that will contain a pair of parallel lines. That is, any two parallel lines must be coplanar.
The lines m and n in the figure are <em>skew</em>, non-intersecting and non-parallel. They cannot be contained in a single plane.

<em>Additional comment</em>
Three or more parallel lines may not be coplanar. They will only definitely be coplanar when considered in pairs.
