The median of a triangle divides it into two congruent triangle            (b)  isosceles triangles right triangles                   (d)  triangles of equal areas

Explanation

Let the `triangleABC` in which AD is the median of AC.

Now we can write `BD=DC`

So, `ar(triangleABD)=ar(triangleACD)`

`therefore` area of triangle = `1/2xx`base`xx`height

=`1/2xxBDxxh`

or `1/2xxCDxxh`

So, median of a triangle divides it into two equal areas.

Hence, option(d) is correct.
