The median divides a triangle into two Triangles of equal areas.
=========================================================
Given:
AD is a median of ∆ABC & E is any point on AD.
To Prove:
ar (ABE) = ar (ACE)Proof:
Since,AD is median of ΔABC.
Thus, it will divide ΔABC into two triangles of equal areas.
∴ ar(ABD) = ar(ACD) — (i)
Also,
ED is the median of ΔEBC.
∴ ar(EBD) = ar(ECD) — (ii)
On Subtracting eq (ii) from (i),
ar(ABD) – ar(EBD) = ar(ACD) – ar(ECD)
ar(ABE) = ar(ACE)
==========================================================
