The quadrilateral formed by joining the midpoints of the sides of a quadrilateral ABCD, taken in order, is a rhombus, if
(a) ABCD is a parallelogram
(b) ABCD is a rhombus
(c) diagonals of ABCD are equal
(d) diagonals of ABCD are perpendicular to each other
Is quadrilateral ABCD a rhombus?
I. Quadrilateral ABCD is a ||gm.
II. Diagonals AC and BD are perpendicular to each other.
The correct answer is: (a)/(b)/(c)/(d).
In the figure below, the diagonals of the quadrilateral ABCD are perpendicular to each other.
