A trapezoid.
Yes, that sounds right.
Angles that are congruent and supplementary must be right angles.
Only in squares and rectangles. In a rhombus, the consecutive angle is supplementary (sums to 180 degrees).
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.
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.

The Parallelogram Consecutive Angles Conjecture states that the consecutive angles in a parallelogram are supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees. This property follows from the fact that opposite angles in a parallelogram are congruent.
Angles that are congruent and supplementary must be right angles.
They are congruent angles
Only in squares and rectangles. In a rhombus, the consecutive angle is supplementary (sums to 180 degrees).
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.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Consecutive angles are supplementary Diagonals bisect each other Opposite angles are congruent Opposite sides are parallel
If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.
Consecutive angles of a parallelogram are supplementary.
