Find k, if PQ || RS and P(2,4), Q (3,6), R (3,1), S(5,k).

Find k, if PQ||RS and P(2,4), Q(3,6), R(3,1) and S(5,k).

Find the value of k if line PQ will be parallel to line RS where P(2, 4), Q(3,6), R(8,1), S(10, k)

If coordinates of P,Q,R,S and (3,6,4),(2,5,2),(6,4,4),(0,2,1) respectively, find the projection of PQ on RS.

Find the value(s) of k so that PQ will be parallel to RS. Given : P(2, 4), Q(3, 6), R(8, 1) and S(10, k)

If P,Q,R,S are the points (-2,3,4),(-4,4,6),(4,3,5),(0,1,2) prove by projection that PQ is perpendicular to RS.

If the points P,Q,R,S are (4,7,8),(-1,-2,1),(2,3,4) and (1,2,5) respectively show that PQ and RS intersect. Also find the point of intersection.
