No. An isosceles trapezium (isosceles triangle with its apex removed) would have congruent diagonals but it is not a parallelogram.

The diagonals of a rhombus are always congruent. A rhombus is a quadrilateral with all sides of equal length.

This property distinguishes a rhombus from other quadrilaterals like rectangles or parallelograms.

Is the diagonals of rhombus congruent?

"Congruent" isn't used to describe the diagonals of a rhombus. However, all four sides of a rhombus are congruent - they are all the same length.The diagonals of a rhombus are perpendicular to each other. They are not the same length - if the diagonals were the same length, then you would have a square.
