Why isn't a kite a parallelogram?

• Parallelograms have congruent opposite sides and a kite does not.

• Kites are parallelograms.

• Parallelograms have two sets of consecutive congruent sides and kites do not.

Why are consecutive angles in parallelogram supplementary

• Parallelograms have parallel opposite sides. If the lines are parallel then consecutive interior angles are supplementary.

• They are not supplementary they are actually congruent.

• Parallelograms have a parallel sides. If the lines are parallel then consecutive exterior angles are supplementary.
