D and E are the mid-points of the sides AB and AC of `Delta`ABC and O is any point on side BC. O is joined to A. If P and Q are the mid-points of OB and OC respectively, then DEQP is

Dand E are the mid-points of the sides AB and AC of DeltaABC and O is any point on side BC. O is joined to A. If P and Q are the mid-points of OB and OC respectively, then DEQP is

D, E and F are the mid-points of the sides AB, BC and CA respectively of A ABC. AE meets DF at O. P and Q are the mid-points of OB and OC respectively. Prove that DPOF is a parallelogram.

P, Q, R are the midpoints of the sides AB, BC and CA of the triangle ABC and O is a point within the triangle, then OA + OB + OC =

If D,E and F are the mid-points of the sides BC,CA and AB, respectively of a DeltaABC and O is any point, show that (i) AD+BE+CF=0

P is any point on the side BC of a triangle ABC . P is joined to a. If D and E are the midpoints of the sides AB and AC respectively and M and N are the midpoints of BP and CP respectively then quadrilateral DENM is

If P, Q , R are the mid-points of the sides AB, BC and CA of Delta ABC and O is point whithin the triangle, then vec (OA) + vec(OB) + vec( OC) =

D and E , are the mid-points of AB and AC of Delta ABC, BC is produced to any point P. DE, DP and EP are joined, then Delta PED is equal to ?
