Given: a quadrilateral whose diagonal AC divides it into two parts, equal in area.

Here,

A quadrilateral is any shape having four sides, it is given that diagonal AC of the quadrilateral

divides it into two equal parts.

We know that the rectangle, parallelogram and rhombus are all quadrilaterals, in these

quadrilaterals if a diagonal is drawn say AC it divides it into equal areas.

∵ This diagonal divide the quadrilateral into two equal or congruent triangles.
