This is all about the vocabulary. First, quadrilateral, ok so a quadrilateral is a shape with four sides. Next, congruent; congruent basically means equal. So we can say what shape has four equal sides and right angles? Your basic shapes with four sides would be a trapezoid, a parallelogram, a rhombus, a rectangle or a square. The square is the only one of these that fits.
Rhombus. Because a Rhombus has four congruent sides but no right angles.
Rhombus
Square
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.
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
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.
rhombus
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
A rhombus.
Rhombus
Square
A rhombus.
It is a rhombus that has 4 equal sides but no right angles.
