No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.
Yes because a rhombus is like a parallelogram
square
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.
No because the diagonals of a parallelogram are of different lengths
They are sometime congruent because a square is a parallelogram and its sides are congruent and a rectangle is one and its sides aren't congruent.
rectangle and parallelogram
Yes because a rhombus is like a parallelogram
square
No. The diagonals are perpendicular, but they dont have to be congruent.
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.
Yes the diagonals of a square are always congruent. Their length is a*root 2 where a is the side of the square.
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.

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.

No sucka
Regular polygons. A square and rectangle will have congruent (equal length) diagonals.
