Ordinarily, yes: one is acute (less than 90 degrees) and one is obtuse (more than 90 degrees), such that their sum is 180 degrees.
The exception is if both angles are right angles (2 x 90 degrees).
No, a trapezoid does not have four obtuse angles. A trapezoid has one pair of parallel sides and the other pair of non-parallel sides. The angles of a trapezoid can be a combination of acute, obtuse, and right angles, but it cannot have four obtuse angles.
No, a trapezoid cannot have two obtuse angles. By definition, a trapezoid has exactly one pair of parallel sides. If it had two obtuse angles, it would imply that both pairs of opposite angles are obtuse, which is not possible as one pair of opposite angles must be acute in a trapezoid.
Angles are usually illustrated as two acute and two obtuse, but there can be two right, one acute and one obtuse. Angles cannot be parallel since that is a characteristic of lines, not angles!
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
No,neither one can, since by definition a pair of complementary angles add to 90 degrees
True , but remember there cannot be two obtuse. Must be one acute & one obtuse. * * * * * NOT always true. Both may be right angles.
The two angles of a linear pair must add to 180 degrees. So if one is less than 90 degrees (acute) the other must be more than 90 degrees (obtuse).
Every pair of supplementary angles includes one obtuse angle?

One pair of equal acute angles and a pair of equal supplementary (obtuse) angles.

If the 2 acute angles are equal and the 2 obtuse angles are equal then it could be a 4 sided quadrilateral in the form of a parallelogram or a rhombus

No.No.No.No.
