and are the vertices of a and AD is its median. Prove that the median AD divides into two triangles of equal areas.

Solution:
D is midpoint of BC, so find its coordinates using below:
Midpoint formula:
Find area of triangle ABD:
We know that:
Area of a triangle
So,
Area of triangle ABD:
sq. units .......
Area of triangle ACD:
sq. units ........
From and , we conclude that Area of triangle ABD and ACD is equal.
Hence proved.
