Question

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

Explanation:

Skew lines are non - parallel and non - intersecting lines that exist in 3 - D space. Since planes Q and R are parallel, lines a and b which lie in these different parallel planes cannot intersect. Also, as shown, they are not parallel to each other. So, they are skew.

Answer:

Lines a and b are skew because they are in parallel planes (Q and R), do not intersect, and are not parallel to each other.
