✪ Given : In quadrilateral MORE, N is mid point on diagonal MR.
✪ To prove : ar(MONE) = ar(ENOR)
✪ Proof : In ∆MER, since median EN divides triangles into two equal areas.
ar(∆MEN) = ar(∆ENR) _(i)
In ∆MOR, since median ON divides triangle into two equal areas.
ar(∆MON) = ar(∆NOR) _(ii)
By adding equation (i) and (ii) we get,
ar(∆MEN) + ar(∆MON) = ar(∆ENR) + ar(∆NOR)
ar(MONE) = ar(ENOR)
