They are quadrilaterals which have two pairs of parallel sides.
Quadrilaterals. Parallelograms have two pairs of parallel sides.
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
Kites and trapzuims.
quadrilaterals with two pairs of parallel sides
The four quadrilaterals that are symmetrical and have two pairs of parallel sides are:SquareRectangleRhombusParallelogram
parallelogram
Quadrilaterals with two pairs of parallel sides: Rhombus Parallelogram Rectangle Square
A trapezoid has one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs of parallel sides.
quadrilaterals with two pairs of parallel sides
Two different quadrilaterals have two pairs of parallel sides and have all their angles congruent. They are the square and the rectangle.
The two quadrilaterals are squares.
There are lots of different quadrilaterals that do not have two pairs of parallel sides: a kite, arrowhead, trapezium, and a shape which has no specific name.
Trapezoid.
Quadrilaterals with two sets of parallel sides are parallelograms. Parallograms include squares, rectangles, and rhombi (rhombuses).
Any that are not a parallelogram (rhombus, rectangle, square). These would include all irregular quadrilaterals as well as trapezoids (trapeziums) which have only one set of parallel sides.
