true.
Not necessarily. But a parallelogram with perpendicular diagonals must always be one.
If the diagonals are congruent and are perpendicular bisectors of each other then the parallelogram is a square. If the diagonals are not congruent but are perpendicular bisectors of each other then the figure would be a rhombus.
No. It is false. If both of those conditions are met, then the quadrilateral is a square.

No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).
diagonals are perpendicular
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.
rhombus
It is a rhombus
They become the diagonals of a parallelogram.
No, the diagonals of a parallelogram are not normally congruent unless the parallelogram is a rectangle.
They must be otherwise they would not be diagonals.
diagonals.
No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.
A parallelogram is a rhombus if and only if the diagonals are perpendicular
The diagonals of a parallelogram are parallel and the same length.
