If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
If consecutive angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
If all pairs of consecutive angles of a quadrilateral are supplementary the the quadrilateral is a parallelogram?
True
Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
What the opposite angles of an inscribed quadrilateral?
Supplementary
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
Is this statement true or falseIf a quadrilateral is a parallelogram, then its opposite angles are always supplementary?
false
If consecutive angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
What quadrilateral has 2 pairs of supplementary angles?
A parallelogram.
If a quadrilateral is a parallelogram then its consecutive angles are?
Then it's consecutive angles are supplementary.
If all pairs of consecutive angles of a quadrilateral are supplementary the the quadrilateral is a parallelogram?
True
If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is not a parallelogram?
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
If a quadrilateral is a parallelogram then its opposite angles are always supplementary?
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.
If a parallelogram is inscribed in a circle it must be a rectangle?
Yes, a parallelogram inscribed in a circle must be a rectangle. This is because a circle's inscribed angle theorem states that the opposite angles of a cyclic quadrilateral (a quadrilateral inscribed in a circle) must be supplementary. In a parallelogram, opposite angles are equal, which can only hold true if all angles are right angles, thus making the parallelogram a rectangle.
Are the opposite sides of a parallelogram supplementary?
Yes, the opposite sides of a parallelogram are equal in length, but they are not supplementary. Supplementary angles refer to two angles whose measures add up to 180 degrees. In a parallelogram, consecutive angles are supplementary, meaning each pair of adjacent angles sums to 180 degrees, while opposite angles are equal but not supplementary.
