If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
Are adjacent angles in a parallelogram are supplementary?
Adjacent angles in a parallelogram are supplementary.
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
If a parallelogram has one right angle then all of its angles must be right?
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
Does a rhombus have opposite angles that are supplementary?
No. The adjacent angles are supplementary.
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
Are all angles of parallelogram are congruent?
The answer is no. Opposite angles are congruent, Consecutive angles are supplementary.
Are adjacent angles in a parallelogram are supplementary?
Adjacent angles in a parallelogram are supplementary.
How Dow you that the opposite angles of a parallelogram are equal?
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.
