[" In a triangle "OAC," if "B" is the mid-point of side "AC" and "vec OA=vec a,vec OB=vec b" ,then what "],[" is "vec OC" ? "]

In a triangle OAC, if B is the mid point of side AC and vec O A= vec a , vec O B= vec b , then what is vec O C ?

In a triangle OAC, if B is the mid point of side AC and vec O A= vec a ,\ vec O B= vec b ,\ then what is vec O C ?

In a triangle OAC, if B is the mid point of side AC and vec(OA)=veca,vec(OB)=vecb , then what is vec(OC) .

Let O be an interior point of Delta ABC such that 2vec OA+5vec OB+10vec OC=vec 0

If D is the mid-point of the side BC of a triangle ABC, prove that vec AB+vec AC=2vec AD .

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

OABC is a tetrahedron D and E are the mid points of the edges vec OA and vec BC. Then the vector vec DE in terms of vec OA,vec OB and vec OC

ABC is any triangle and D,E,F are the mid-points of sides vec(BC),vec(CA) and vec(AB) respectively. Express the vec (BE) and vec (CF) as linear combination of vectors vec (AB) and vec (AC) .

If | vec AO + vec OB | = | vec BO + vec OC |, then A, B, C form

Statement 1: In Delta ABC,vec AB+vec BC+vec CA=0 Statement 2: If vec OA=vec a,vec OB=vec b, then vec AB=vec a+vec b
