planes q and r are parallel. explain how you know lines a and b are skew.

Brief Explanations:

Skew lines are non - parallel and non - intersecting. Since planes Q and R are parallel, lines a and b in different parallel planes cannot intersect. Also, they are not parallel as their directions are different. So, lines a and b are skew.

Answer:

Lines a and b are in different parallel planes (Q and R), so they cannot intersect. Also, they are not parallel as shown by their orientation in the planes, thus they are skew.
