No but all parallelograms are trapezoids
Yes because a trapezoid is US term while a trapezium is a UK term
No, because trapeziums (aka trapezoids) have only one pair of parallel sides, while parallelograms have two pairs.
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.

Kites, trapezoids, trapeziums, and self-intersecting/complex quadrilaterals.
No, because trapeziums (aka trapezoids) have only one pair of parallel sides, while parallelograms have two pairs.
Quadrilaterals include trapeziums, trapezoids, parallelograms, rhombuses, rhomboids, rectangles, and squares.

Yes
Line up the two trapeziums side by side with their parallel sides top and bottom, and with a pair of corresponding sides of the trapeziums facing one another. Flip one of them top to bottom and bring the two trapeziums together. They will form a parallelogram.Line up the two trapeziums side by side with their parallel sides top and bottom, and with a pair of corresponding sides of the trapeziums facing one another.

No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
trapezoids and rectangles, are both quadrilateral (which means shapes with 4 sides). rectangles and trapezoids are also polygons.
If both sides are parallel, the figure can be a square, rectangle, rhombus, or parallelogram. If only one side is parallel, the figure can be a trapezoid, or isosceles trapezoid. In Britain, trapezoids are called trapeziums.
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.
