ABCD is a quadrilateral whose diagonal AC divides it into two parts equal in area then ABCD :
If diagonal divides into two parts then it forms a triangle.
It may be kite
The median of a triangle divides it into two :
Median of a triangle is a line segment joining vertex to the mid point of the opposite side. Thus a median of a triangle divides it into two triangles of equal area.
If ABCD is a parallelogram, then which of the following is true ?
(opposite sides of parallelogram)

In the figure, AB || DC. Which of the following is true about the figure ?
So area of = area of
(Triangles on the same base are equal)
A rectangle and a rhombus are on the same base and between the same parallels. Then the ratio of their areas is :
Since a rectangle and a rhombus are on the same base and between the same parallels, their areas are equal. So, the ratio is 1:1
