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

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

Reason: two parallel lines are coplanar, so a line parallel to l can (and must) lie in the same plane as l (for example, draw p in plane A parallel to l).
