Q : 1 In Fig. , E is any point on median AD of a . Show that.
We have ABC such that AD is a median. And we know that median divides the triangle into two triangles of equal areas.
Therefore, ar(ABD) = ar( ACD)............(i)
Similarly, In triangle BEC,
ar(BED) = ar (DEC)................(ii)
On subtracting eq(ii) from eq(i), we get
ar(ABD) - ar(BED) =
Hence proved.
