No, they are generally not supplementary.
Not normally but quite possible in the form of an isosceles trapezoid.
The answer is supplementary! :-)
No. The adjacent angles are supplementary.
'never'
No, they are equal. Adjacent angles are supplementary in a prallelogram.
Yes.
A trapezoid.

Wouldn't think so, think of a trapezium shaped like a square with a triangle on one side... The angles at one end of the figure are both 90o, and the angles at the other end will be supplementary, but not opposite angles.
No. The adjacent angles are supplementary.
Yes because that is one of the properties of a trapezoid
'never'
they are all complementary
No, they are equal. Adjacent angles are supplementary in a prallelogram.
Yes, adjacent angles are supplementary; however, opposite angles are not.
A trapezoid is a quadrilateral with at least one pair of parallel sides, while a parallelogram is a specific type of trapezoid where both pairs of opposite sides are parallel. This means that all angles in a parallelogram are supplementary, and its opposite angles are equal, whereas a trapezoid does not have these properties. Additionally, the diagonals of a parallelogram bisect each other, but this is not necessarily true for trapezoids.
