All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular.
The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

Do all squares have two pairs of parallel sides?
Yes the sides are all the same as well too.
What quadrilaterals have two parallel sides'?
Squares, rectangles, parallelograms and rhombuses have two parallel sides. The other two are also parallel. A trapezium has only two parallel sides.
Why can all squares be classified as parallelograms but not all parallelograms can be classified as squares?
A parallelogram is a four-sided figure with opposite sides parallel. Squares and rectangles are two examples of parallelograms. A square is a four-sided figure that has four equal sides, and opposite sides are parallel.
What is the main difference between squares and trapezoids?
The main difference between squares and trapezoids is that, while the length all four sides of a square are equal, trapezoids have two sides with equal length and two sides of different length. Also, the opposite pairs of sides in a square are parallel, while only one pair of sides in a trapezoid is parallel.
What other name is for a rectangle?
Rectangles are quadrangles, polygons with four sides. A rectangle is a quadrangle with two long sides and two short sides, and the long sides and short sides are parallel to each other. They are parallelograms, in which opposite sides are parallel. Note: All squares are also rectangles.
Do all squares have two pairs of opposite sides that are parallel?
Yes.

Two quadrilaterals that have two pairs of parallel sides each In addition all four of the sides are congruent in both shapes?
The two quadrilaterals are squares.
Does a rectangle have to be long?
No, it just has to have two pairs of parallel sides. By this definition all squares are also rectangles.
What two quadrilaterals have opposite sides equal and parallel?
parallelograms and squares.

What quadrilateral has two pairs of parallel sides and four equal sides?
Any rhombus has. That includes squares.
Do parallelograms have parallel sides?
Yes. A Parallelogram is a quadrilateral that has two pairs of parallel sides which are opposite each other and of equal length, though the pairs may be of different length to each other. If the angles are all 90° then the parallelogram is also a rectangle. If the angles are all 90° AND all sides are equal then the parallelogram is also a square. All squares are rectangles, but not all rectangles are squares; Similarly all squares are rhombuses but not all rhombuses are squares And all rhombuses, and thus squares, are parallelograms, but not all parallelograms are rhombuses (nor squares).
What shape with 4 sides has 2 pairs of parallel sides?
Quadrilaterals with two sets of parallel sides are parallelograms. Parallograms include squares, rectangles, and rhombi (rhombuses).
