Prove using vectors: The diagonals of a quadrilateral bisect each other iff it is a parallelogram.

Prove that; If the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus.

If the diagonals of a quadrilateral bisect each other at right angle, prove that the quadrilateral is a rhombus. A rhombus has all its four sides equal.

If one diagonal of a quadrilateral bisects the other, then it also bisects the quadrilateral.
