A square.

Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
A rhombus is a quadrilateral with four congruent sides. The opposite angles are congruent but not necessarily 90 degrees.
A square.
A square because that is the only possible figure that can have two congruent sides and four right angles.
A square.
A figure with four congruent angles is a rectangle. In a rectangle, all four angles are right angles and therefore congruent to each other.
All right angles are congruent, and all straight angles are congruent.

A right trapezoid can have no congruent sides and two right angles.
Angles that are congruent and supplementary must be right angles.
A quadrilateral with 4 right angles cannot have just two congruent sides so, unless this is a trick question (2 congruent sides does not excluded the possibility of more than 2 congruent sides), the answer is there is no such plane figure.
For a figure to be a square, it must have four congruent sides and four right angles. For a figure to be a rectangle, it only has to have four right angles.
right angles
A rhombus is a parallelogram with all four sides congruent to each other with no right angles. A square is a parallelogram with four congruent sides and four right angles.
