OABC is a tetrahedron andOA=a,OB=b and OC=c. The points P and Q are such that OA=AP and 2OB=BQ. The point M is the midpoint of PQ. Find (i) AB, (ii) PQ, (iii) CQ, (iv) QM, (v) MB and (vi) OM in terms of a, b and c.

In a parallelogram ABCD, P divides AB in the ratio 2:5 and Q divides DC in the ratio 3:2. If AC and PQ intersect at R. Find the ratio AR:RC and PR:RQ.

ABCD is a plane quadrilateral and E is any point on AD. EF is drawn parallel to DB to meet AB in F and EG is drawn parallel to DC to meet AC in G. Prove that FG is parallel to BC.
