False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.

No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).

Not necessarily. But a parallelogram with perpendicular diagonals must always be one.
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.
False. It could be a rhombus.
It is a square because its diagonals are equal in length and they bisect each other at right angles which is 90 degrees The diagonals of a rhombus are not equal in length but they meet at right angles.
No. It is false. If both of those conditions are met, then the quadrilateral is a square.
False. ^^^ Wronnngg! Its True (Apex). ^ No you are wrong, It is false.
No, a quadrilateral with congruent diagonals but no right angles is not necessarily a parallelogram. In order for a quadrilateral to be classified as a parallelogram, it must have both pairs of opposite sides parallel. The property of having congruent diagonals does not guarantee that the sides are parallel, so the quadrilateral may not be a parallelogram.
