No. An isosceles trapezium (isosceles triangle with its apex removed) would have congruent diagonals but it is not a parallelogram.
All quadrilaterals have 2 diagonals
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.
Four sided quadrilaterals have two diagonals.

Quadrilaterals only have two diagonals because they only have four vertices.
Quadrilaterals only have two diagonals because they only have four vertices.
A square, a rhombus and a kite are all 4 sided quadrilaterals that have perpendicular diagonals.
All quadrilaterals have 2 diagonals.
All quadrilaterals have 2 diagonals
Quadrilaterals have four sides so the only possible answer to this question is that a quadrilateral only has two diagonals.
they are called parallelogram in which diagonals are equal
square
Rectangles
Not generally.
