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.
They are quadrilaterals which have two pairs of parallel sides.
Quadrilaterals like Parallelogram(Square,rectangle), Rhombus have oppsite sides parallel to each other.
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.

They are quadrilaterals which have two pairs of parallel sides.
A trapezoid has one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs of parallel sides.
Quadrilaterals like Parallelogram(Square,rectangle), Rhombus have oppsite sides parallel to each other.
The four quadrilaterals that are symmetrical and have two pairs of parallel sides are:SquareRectangleRhombusParallelogram
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
Quadrilaterals usually have special names only if they DO have parallel sides, or some other special property. You might just call it "quadrilateral", or "a quadrilateral with no parallel sides".
There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.
Yes
Sometimes, but not necessarily.
Trapezoids make up the set of quadrilaterals with 2 pairs of parallel sides.
