" व) किसी "Delta ABC" में सिद्ध कीजिए कि ":vec AB+vec BC+vec CA=0

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

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

If vec a,vec b,vec c are position vectors of the vertices A,B and C respectively,of a trriangle ABC, write the value of vec AB+vec BC+vec CA

Let G be the centroid of Delta ABC , If vec(AB) = vec a , vec(AC) = vec b, then the vec(AG), in terms of vec a and vec b, is

Let G be the centroid of Delta ABC , If vec(AB) = vec a , vec(AC) = vec b, then the vec(AG), in terms of vec a and vec b, is

If P is a point inside Delta ABC such that BC(vec PA)+CA(vec PB)+AB(vec PC)=vec O then P is the .....

Let D, E and F be the middle points of the sides BC,CA and AB, respectively of a triangle ABC. Then prove that vec AD+vec BE+vec CF=vec 0
