In the given figure, E is any point on median AD of a ΔABC. What is ar (ABE) ?
ar (ACE)
AD is the median of △ABC. Therefore, it will divide △ABC into two triangles of equal areas.
Therefore, Area (△ABD) = Area (△ACD) ... (1)
ED is the median of △EBC.
Therefore, Area (△EBD) = Area (△ECD) ... (2)
On subtracting equation (2) from equation (1), we obtain
Area (△ABD) − Area (△EBD) = Area (△ACD) − Area (△ECD)
Area (△ABE) = Area (△ACE)
