Angles and sides are congruent when they are identical. A shape with four identical sides and angles is a square.
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
Any polygon with four or more sides can have parallel sides.

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.

a square!
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
Trapezoid
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
A rectangle is a shape that has four sides with two parallel lines.
