No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.

Adjacent angles in a parallelogram are supplementary.

false

Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.

The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.

No. Opposite angles are equal. Adjacent angles are supplementary.

First of all, you know the opposite sides of a parallelogram are equal because of the definition of a parallelogram. Therefore, two adjacent angles in the parallelogram are supplementary, because same-side interior angles in two parallels and a transversal are always supplementary. Therefore, opposite angles in a paralellogram are equal, because two angles both supplementary to a third angle are equal to each other.

True

false

Consecutive angles are supplementary Diagonals bisect each other Opposite angles are congruent Opposite sides are parallel

False because it will have 2 equal opposite obtuse angles and 2 equal opposite acute angles with the 4 angles adding up to 360 degrees.

Yes, when they are both 90o and the parallelogram is usually referred to as a rectangle.

Opposite sides are congruent Opposite sides are parallel Opposite angles are equal Consecutive angles are supplementary Diagonals bisect each other Diagonals form 2 equal triangles

Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
