A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.

A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
A quadrilateral whose diagonals bisect each other at right angles is a rhombus. each other at right angles at M. So AB = AD and by the first test above ABCD is a rhombus. 'If the diagonals of a parallelogram are perpendicular, then it is a rhombus
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.
The diagonals will cross each other half way at right angles.
A parallelogram that is not a square is any parallelogram whose angles are not ninety degrees or whose opposite sides are not equal.
The diagonals of a rhombus (not rombhus) bisect one another at right angles. The sides of the rhombus form the hypotenuses of triangles whose other sides are half the diagonals. So use Pythagoras.
It is the parallelogram whose angles are right angles.
