If the position vectors of the vertices of a triangle are vec(O), vec(a) and vec(b) and Delta is its area, then prove that 4 Delta^(2)= |vec(a)|^(2) |vec(b)|^(2)- (vec(a).vec(b))^(2) .

Let vec(C ) = vec(A) + vec(B) ,

If G is the centroid of Delta ABC, G' is the centroid of Delta A' B' C' then vec(A)A' + vec(B)B' + vec(C)C' =

If vec(C) = vec(A) + vec(B) then

If G is the centroid of Delta ABC then vec(G)A + vec(G)B + vec(G)C =

Observe the following statements: Assertion (A) : If vertices of a triangle are A(vec(a)), B(vec(b)), C(vec(c )) , then length of altitude through A is (|vec(a) xx vec(b) + vec(b) xx vec(c)+ vec(c ) xx vec(a)|)/(|vec(b)-vec(c )|) Reason (R ): Area of triangle is Delta = (1)/(2) (Base) (Height) = (1)/(2) |vec(AB) xx vec(AC)|

If |vec(a)|=sqrt3, |vec(b)|=2, (vec(a), vec(b))= (pi)/(3) , then the area of the triangle with adjacent sides vec(a) + 2vec(b) and 2vec(a) + vec(b) (in sq.u) is

If the vectors vec(a), vec(b), vec(c ) form the sides vec(BC), vec(CA), vec(AB) respectively of triangle ABC then show that vec(a) xx vec(b) = vec(b)xx vec(c ) = vec(c ) xx vec(a) .

a, b are the magntidues of vectors vec(a) " & " vec(b) . If vec(a) xx vec(b) = 0 the value of vec(a). vec(b) is
