Quick math question? :) *10 POINTS*?

Just staring at the picture I see that all four edges of the rectangle NPKJ are skew to QR, as are the segments JL, KM, and LM. The other five segments intersect QR either at Q or at R. So the ones skew to QR are just the segments NP, PK, KJ, JN, JL, KM, LM. (Of course you could name each one of these segments differently by reversing the order of the points in the name.)
