`A=(1,-1,2),G=(3,1,1)` are one vertex and centroid of tetrahedron `ABCD` and `G_(1)` is the centroid of `/_BCD` then `AG_(1)=`

A=(1,-1,2),G=(3,1,1) are one vertex and centroid of tetrahedron ABCD and G_1 ,is the centroid of DeltaBCD then AG_(1)=

In the tetrahedron ABCD, A=(1,2,-3) and G(-3,4,5) is the centroid of the tetrahedron. If P is the centroid of the Delta BCD then AP=

Q.if (2,-1,2) is the centroid of tetrahedron (OABC)/(|bar(O)G_(1)|=)=

If G is the centroid of Delta ABC and AG-BC, then /_BGC is :

the vertex of triangle are A(1,4,7),B(2,6,3) and C(-2,5,8) then centroid

A(1,-2,3),B(2,1,3),C(4,2,1) and G(-1,3,5) is the centroid of the tetrahedron ABCD if P=D_(y) and q=D_(z) then 13p-11q=

The centre of a square ABCD is at z=0, A is z_(1) . Then, the centroid of /_\ABC is (where, i=sqrt(-1) )

If A(2, -2, 3), B(x, 4, -1), C(3, x, -5) are the vertices and G(2, 1, -1) is the centroid of triangleABC , then x=

If A(a,2,2),B(a,b,1) and C(1,2,-2) are the vertices of triangle ABC and G(2,1,c) is centroid, then values of a,b and c are

A(1,1,3) , B(4,3,2) and C(5 ,2, 7) are three vertices of a tetrahedron for which the centroid is (4 , 5/2 , 5) the fourth vertex is
