(b)The centroid of a triangle ABC is at the point (1,2,3).If the coordinates of A and B are (3,-5,7) and (-1,7,-6) respectively.Find the coordinates of the point C.

The centroid of the triangle ABC is at the point (1,2,3) . If the coordinates of A and B are (3,-5,7) and (-1,7,-6) respectively. Find the coordinates of the point C.

The centroid of a triangle ABC is at the point (1,1,1) , If the coordinates of A and B are (-3,-5,7 ) and (-1,7,6) respectively, find the coordinates of the point C .

If the centroid of the triangle ABC is (1,1,1) and A and B are (3,-5,7) , (1,1,2) then find the coordinate of C.

The coordinates of the vertices of a triangle are(-1,5),(3,7),(1,1).Find the coordinates of its centroid.

Draw the coordinate axes and mark the points A(1,1) , B(7,1) .

If coordinates of the circumcentre and the orthocentre of a triangle are respectively (5, 5) and (2, 2), then the coordinates of the centroid are

The sides of ABCD are parallel to the coordinate axes and A (3,7), C(7, 9)are the opposite vertices.Write the coordinates of B and D.

If the vertices A,B,C of a triangle ABC are (1,2,3),(-1,0,0),(0,1,2)respectively,then find /_ABC.
