Question

Planes A and B are shown.

Planes B and A intersect. Plane B is vertical and contains vertical line n. Plane A is horizontal and contains horizontal line m. Lines m and n are perpendicular. Line l is on plane A and it is slightly diagonal.
If a new line, p, is drawn parallel to line l, which statement is true?

Line p must be drawn in plane B.
Line p must be perpendicular to line m.
Line p must be drawn so that it can lie in the same plane as line l.
Line p must be drawn in the same plane as line n.

Answer 1

Answer: "Line p must be drawn so that it can lie in the same plane as line l."

Reason: Parallel lines are coplanar, so any line parallel to l must lie in a plane with l (you can draw p in plane A parallel to l). The other choices are not required.
