An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.

a rectangle

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' Congruent AnglesIt's not the adjacent angles of a rhombus that are congruent, but the diagonal ones.

A kite is a quadrilateral with two pairs of adjacent congruent sides. The angles between the unequal sides are equal.

square

A General Quadrilateral

A rectangle has two pairs of congruent sides, but any pair of adjacent sides is non-congruent.

they have 4 congruent angles

A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.

A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral

False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.

No. It can also be a kite.If one pair of adjacent sides of a parallelogramare congruent, then the quadrilateral is a rhombus.

your mom, and your cousin

For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.

Rectangles have congruent adjacent angles.

It can also be a kite. That has two congruent pairs of sides but unlike a parallelogram they are adjacent, not opposite. A parallelogram with congruent diagonals is a rectangle.

A rhombus.

- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.

A quadrilateral has four interior angles. It may have two, three, four, or none of them congruent.

A quadrilateral is any polygon with 4 sides - and hence with 4 angles. Those angles may, or may not, be congruent.A quadrilateral is any polygon with 4 sides - and hence with 4 angles.

A quadrilateral is a plane figure with four straight sides and does not necessarily have any congruent angles. Some quadrilaterals such as, squares, rectangles, rhombuses, and parallelograms do have congruent angles.
