If vecu , vecv and vecw be the position vectors of the vertices A,B and C of the DeltaABC find the area of the triangle.

If bar(a), bar(b), bar(c) are the position vectors of the vertices A, B, C respectively of DeltaABC then find the vector equation of the median through the vertex A.

In Delta ABC, if bar(a), bar(b), bar(c) are position vectors of the vertices A, B, and C respectively, then prove that the position vector of the centroid G is (1)/(3) (bar(a) + bar(b) + bar(c))

If the position vector of the vertices A,B and C of a DeltaABC be (hati + 2hatj + 3hatk), (2hati + 3hatj + hatk) and (3hati + hatj +2hatk) respectively, prove that DeltaABC is equilateral.

If vec a ,\ vec b ,\ vec c are position vectors of the vertices of a triangle, then write the position vector of its centroid.

If vec a,vec b,vec c are position vectors of the vertices of a triangle,then write the position vector of its centroid.

If A, B, C are the vertices of a triangle whose position vectros are vec a,vec b, vec c and G is the centroid of the DeltaABC, then overline(GA)+overline(GB)+overline(GC) =
