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.
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
No, they are equal. Adjacent angles are supplementary in a prallelogram.
'never'
they are all complementary
Yes, adjacent angles are supplementary; however, opposite angles are not.
Yes, the opposite sides of a parallelogram are equal in length, but they are not supplementary. Supplementary angles refer to two angles whose measures add up to 180 degrees. In a parallelogram, consecutive angles are supplementary, meaning each pair of adjacent angles sums to 180 degrees, while opposite angles are equal but not supplementary.
