No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.
No not normally only if the parallelogram is in the form of a rectangle will it then have congruent diagonals.
If the diagonals are cong. then the figure is a rectangle.
If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.
No, the diagonals of a parallelogram do not necessarily bisect the angles. The diagonals of a parallelogram divide it into four congruent triangles, but they do not necessarily bisect the angles of those triangles.
No, the diagonals of a parallelogram are not normally congruent unless the parallelogram is a rectangle.
No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.
The diagonals are not congruent unless the parallelogram happens to be a rectangle.
If a parallelogram is in the form of a rectangle then both diagonals are congruent in lengths.
No not normally only if the parallelogram is in the form of a rectangle will it then have congruent diagonals.
yes. they are not congruent
No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).
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.
true.
yes
If the diagonals are cong. then the figure is a rectangle.
The diagonals of a parallelogram are congruent (equal in length) and bisect each other.
