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.
no * * * * * But they can be.
