It's not possible to have all sides parallel.
The quadrilaterals that have every side parallel to the one opposite it ...
or two pairs of parallel sides ... are:
-- parallelograms
-- rhombera
-- rectangles
-- squares
Notice that
-- every square is also a rectangle, a rhombus, and a parallelogram.
-- every rectangle is also a parallelogram.
-- every rhombus is also a parallelogram.
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.
No, a triangle will never have parallel sides.
Quadrilaterals are two-dimensional shapes that have four sides. Quadrilaterals that have only one set of parallel sides are called trapezoids.
yes
A trapezoid has one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs of parallel sides.

All quadrilaterals. That is part of the definition of being a quadrilateral.
No. A trapezoid only has one pair of parallel sides. A chevron has no parallel sides.

They are quadrilaterals; opposite sides are parallel.
yes
Yes. All of them do, but the trapezoid is the only one with only one pair of parallel sides.
No. An example of a quadrilateral that doesn't have a pair of parallel sides is a kite.
