In a `!ABC` if a = 7 , b = 8 and c = 9 , then the length of the line joining B to the mid-points of AC is

Find the slope of the line joining the points (7,5) and (9,7) :

Find the mid point of the line joining the points (7, 6) and (-3, -4) .

In triangle ABC , AB = 10 AC = 7 , BC = 9 then find the length find the length of the median drawn from point C to side AB .

In Delta ABC if a=7,b=8,c=9 then the distance from the vertex B to the centroid is

A B C D is a kite having A B=A D and B C=C D . Prove that the figure formed by joining the mid-points of the sides, in order, is a rectangle.

A(3,4),B(-3,0) and C(7,-4) are the vertices of a triangle.Show that the line joining the mid-points of AB and AC is parallel to BC and is half of it.
