A square.
A Rhombus.
A rectangle has two pairs of congruent sides, but any pair of adjacent sides is non-congruent.
A rhombus is a quadrilateral with four congruent sides. The opposite angles are congruent but not necessarily 90 degrees.
it called a square !Square
Rhombus: A Rhombus has four congruent sides but no right angles.
Rhombus. Because a Rhombus has four congruent sides but no right angles.
Yes. It is still a quadrilateral as long as it still has four sides, and they can be congruent if all of the sides are equal. It does not mean that All of the angles have to be right.
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.

A rhombus.

A rhombus.
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
It is a rhombus that has 4 equal sides but no 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.
