Horizontal plane Q and vertical plane R intersect at a line. Lines d and c are vertical and parallel to each other on plane R. Line B is horizontal on plane Q. Line a is diagonal on plane Q.
Marissa says that lines a and d will eventually intersect. Is she correct? Explain.

yes, because they are on the same plane
yes, because they are perpendicular
no, because they are parallel
no, because they are skew

No — because they are skew.

Line a lies entirely in plane Q (the horizontal plane). Line d is vertical in plane R (and so not in Q). They are not parallel and do not meet, so they are skew lines (nonparallel, nonintersecting lines in different planes).
