No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.

No. The diagonals are perpendicular, but they dont have to be congruent.


Is a rhombus always sometimes or never a parallelogram?

Always. In fact, one method of proving a quadrilateral a rhombus is by first proving it a parallelogram, and then proving two consecutive sides congruent, diagonals bisecting verticies, etc.


Are the diagonals of a square always congruent?

Yes the diagonals of a square are always congruent. Their length is a*root 2 where a is the side of the square.


Are the diagonals of a trapezoid always congruent?

No, the diagonals of a trapezoid are not always congruent. A trapezoid is a quadrilateral with at least one pair of parallel sides. The diagonals of a trapezoid connect the non-parallel vertices, and their lengths can vary depending on the specific dimensions of the trapezoid. In a trapezoid where the non-parallel sides are of equal length, the diagonals will be congruent, but this is not always the case.


What quadrilateral does not always have congruent diagonals?

A quadrilateral that does not always have congruent diagonals is a trapezoid. In a trapezoid, which has at least one pair of parallel sides, the diagonals are generally not congruent unless it is an isosceles trapezoid. Other types of trapezoids can have diagonals of different lengths. Thus, congruent diagonals are not a defining characteristic of all trapezoids.


Are diagonals always congruent?

In a quadrilateral, the diagonals are only congruent for rectangles (or squares, which is a special kind of rectangle). Note: they are not congruent for a Rhombus.


Do the point at which the diagonals of a parallelogram intersect is always equidistant from the four vertices?
