A square is a four-sided polygon with two congruent parallel sides.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
Rhombus
Four right angles; opposite sides are parallel; opposite sides are congruent; diagonals are congruent.
A square and a rhombus
A square is a four-sided polygon with two congruent parallel sides.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.

Trapezoid
Yes (the sides are parallel in pairs - two of the sides are parallel, and the other two are parallel among themselves).
Rhombus has four congruent sides.Opposite sides are parallel. congruent is same.
A Rhombus.
Rhombus
rhombus
There are: Squares, which have all four sides parallel and congruent, all four angles are right and congruent, the diagonals bisect each other and are congruent. Trapezoids, which have two of their sides parallel Rhombus, which have all sides congruent, diagonals bisect, and opposite angles are congruent Parallelograms, which have opposite sides congruent and parallel, diagonals bisect Rectangle, which is a square but one pair of opposite sides aren't congruent.
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
