A parallelogram is one of them.
If the diagonals of a quadrilateral are perpendicular to each other, then the quadrilateral is a square.Or a kite.

No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).
It is an isosceles trapezoid.

trapezoid
Any kite or square.
Rhombus rhombus
the anser to this question is a trapiezuim as it could have right angles and its diagonals definatly do not bisect each other
An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
The converse of the rectangle diagonal conjecture states that if the diagonals of a quadrilateral are equal in length, then the quadrilateral is a rectangle, which implies that its corners are right angles. To test if the corners of a quadrilateral are right angles, measure the lengths of the diagonals. If the diagonals are equal, you can conclude that the corners are right angles, confirming that the shape is a rectangle.
