" 2),"C(0,0" ) are the vertices of a triangle.Show that the median from "A" is perpendicular "

A(5,-3),B(8,2),C(0,0) are the vertices of a triangle.Show that the medianfrom A is perpendicular to the side BC.

The point A(0, 0), B(1, 7), C(5, 1) are the vertices of a triangle. Find the length of the perpendicular from A to BC and hence the area of the DeltaABC .

A(2, 3, 1), B(-2, 2, 0) and C(0, 1, -1) are the vertices of the triangle ABC. Show that the triangle ABC is right -angled.

If A (1,2,3) , B(0,1,2) and C (2,1,0) are vertices of a triangle , then the length of the median through A is

Show that the points (2,0), (-2,0) and (0,2) are the vertices of a triangle. Also state with reason the type of the triangle .

If A (-1, 4,2), B(3, -2, 0) and C(1,2,4) are the vertices of the triangle ABC, then the length of its median through the vertex A is-

If (2, 0), (4, 4) and (6, 2) are the vertices of the triangle ABC, then find the lengths of its medians.

If A(-2,4) , B(0,0) and C(4,2) are the vertices of DeltaABC , find the length of the median through A .
