Yes. You can show this by SAS of two right triangles. Consider rectangle ABCD. AD and BC are the same length and AC and BD are the same length because opposite sides are congruent. The angles ADC and BCD are congruent since it is a rectangle and the angles are right angles. So the triangles ADC and BCD are congruent and their hypotenuses (the diagonals of the rectangles) are congruent.
rectangle and parallelogram
A square and a rectangle have diagonals of the same lengths.
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.
Regular polygons. A square and rectangle will have congruent (equal length) diagonals.
congruent
No. The diagonals of a parallelogram are congruent if and only if the parallelogram is a rectangle.

square, rectangle and an isosceles trapezoid.
The diagonals of a rectangle are congruent and they bisect each other.
Yes, a quadrilateral that must contain diagonals that are always congruent and has four right angles is a rectangle. In a rectangle, the diagonals are equal in length, and all interior angles measure 90 degrees. A square, which is a special type of rectangle, also meets these criteria, but a rectangle does not have to be a square.
The diagonals are not congruent unless the parallelogram happens to be a rectangle.
No, the diagonals of a parallelogram are not normally congruent unless the parallelogram is a rectangle.
