If OACB is a parallelogramwith ` vec(OC) = vec a and vec (AB) = vec b, " then " vec(OA)=`

If OACB is a parallelogram with vec OC = vec a and vec AB = vec b then vec OA =

If OACB is a parallelogrma with vec( OC) = vec(a) and vec( AB) = vec(b) then vec(OA) is equal to

If OACB is a parallelogram with vec OC=vec a and vec AB=vec b, then vec OA is equal to

If ABCD is a parallelogram and vec AB = vec a , vec BC= vec b then show that vec AC = vec a+ vec b and vec BD = vec b- vec a .

If ABCD is a parallelogram and vec AB = vec a , vec BC= vec b then give geometrical significance of |quad vec a+ vec b|=|quad vec a- vec b| .

If vec(a)=vec(OA) " and " vec(b)=vec(AB), " then " vec(a)+vec(b) is -

If E is the intersection point of diagonals of parallelogram ABCD and vec( OA) + vec (OB) + vec (OC) + vec (OD) = xvec (OE) where O is origin then x=

If vec(OA)=vecavec(OC)=vecb and area of DeltaOAC is S and a parallelogram with sides parallel to vec(OA) and vec(OC) and diagonal vec(OB)=12veca+4vecb , has area equal to B, then is equal to_________

Statement 1 : In DeltaABC , vec(AB) + vec(BC) + vec(CA) = 0 Statement 2 : If vec(OA) = veca, vec(OB) = vecb , then vec(AB) = veca + vecb

Statement 1 : In DeltaABC , vec(AB) + vec(BC) + vec(CA) = 0 Statement 2 : If vec(OA) = veca, vec(OB) = vecb , then vec(AB) = veca + vecb
