Question

Planes Q and R are parallel. Lines a and b are shown on planes Q and R, respectively.

Planes Q and R are parallel. Plane Q contains line a and plane R contains line b. Both lines are going in different directions.
Which statement is true about lines a and b?

They are parallel lines.
They are perpendicular lines.
They are skew lines.
They will intersect.

Answer 1

They are skew lines.

Reason: Parallel planes do not meet, so a line in one plane cannot meet a line in the other. Since the two lines are not parallel (different directions) and they do not intersect, they are skew — nonparallel, nonintersecting lines not in the same plane.
