# In Fig.9.23, E is any point on median AD of a ∆ ABC. Show that ar (ABE) = ar (ACE).

**Solution:**

We know that the median divides a triangle into two triangles of equal areas. AD is the median for triangle ABC and ED is the median of triangle EBC.

Since AD is the median of ΔABC. Therefore, it will divide ∆ABC into two triangles of equal areas.

Hence, Area (ΔABD) = Area (ΔACD) ... (1)

Similarly, ED is the median of ΔEBC.

Hence, Area (ΔEBD) = Area (ΔECD) ... (2)

Substract equation (2) from equation (1), we obtain

ar (ΔABD) - ar (ΔEBD) = ar (ΔACD) - ar (ΔECD)

Area (ΔABE) = Area (ΔACE)

**Video Solution:**

## In Fig.9.23, E is any point on median AD of a ∆ ABC. Show that ar (ABE) = ar (ACE).

**Summary:**

If E is any point on the median AD of triangle ABC, then Area of (ABE) = Area of (ACE).
