Which quadrilateral always have consecutive angles that are supplementary?

Quadrilaterals
AB
in these quadrilaterals, the diagonals are congruentrectangle, square, isosceles trapezoid
in these quadrilaterals, each of the diagonals bisects a pair of opposite anglesrhombus, square
in these quadrilaterals, the diagonals are perpendicularrhombus, square
a rhombus is always aparallelogram

Accordingly, do consecutive interior angles equal 180?

The consecutive interior angles theorem states that when the two lines are parallel, then the consecutive interior angles are supplementary to each other. Supplementary means that the two angles add up to 180 degrees.

Are consecutive angles of a parallelogram supplementary?

DEFINITION: A parallelogram is a quadrilateral with both pairs of opposite sides parallel. THEOREM: If a quadrilateral has 2 sets of opposite angles congruent, then it is a parallelogram. * THEOREM: If a quadrilateral has consecutive angles which are supplementary, then it is a parallelogram.
