Any rectangle.
i think its a trapezoid...
A rectangle. Note: a square is a regular rectangle where all sides are equal; in this case not only are the diagonals equal and bisect each other, they also bisect perpendicularly, that is at 90o to each other.

true
The missing word is "bisect".
Congruent and they bisect each other too.

diagonals.
All quadilatrals have diagonals that bisect each other.
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
They are perpendicular and therefore bisect each other at right angles

I think this is impossible the diagonals of a four sided figure will cross
