Here, we have LO and LM sharing a right angle, this makes them perpendicular.
LO and QN, are two lines that do not intersect and are not parallel, then, they're skew to each other.
LM and ON are parallel (//)
KJMQ are non-coplanar points(They don't share the same plane).
The points P. O, and N are coplanar, but non-collinear.
