Yes because that is one of the properties of a trapezoid
A trapezoid.
Two right angles would always be supplementary because the sum of their angles is 180 degrees.
Yes because supplementary angles add up to 180 degrees
This is not a trapezoid. For all trapezoids (in plane Geometry), the two sets of side angles must be supplementary, or add to 180. No two angles given are supplementary.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
'never'
A trapezoid.
Two right angles would always be supplementary because the sum of their angles is 180 degrees.
They can be but not always because supplementary angles add up to 180 degrees.
Yes because supplementary angles add up to 180 degrees
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.

No, a pair of angles that are supplementary will always have a sum of 180 degrees, while a pair of angles that are congruent will have the same measure. Therefore, it is not possible for a pair of angles to be both supplementary and congruent.
No, a trapezoid cannot have two acute angles and two obtuse angles. By definition, a trapezoid has only one pair of parallel sides. In a trapezoid, the non-parallel sides are always supplementary, meaning they add up to 180 degrees. Therefore, having two obtuse angles would make it impossible for the other two angles to be acute and still satisfy the properties of a trapezoid.
Yes.
No, angles that form a linear pair are supplementary.
