False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.

The opposite angles of a quadrilateral inscribed in a circle have a sum of 180 degrees.
Supplementary
A quadrilateral is inscribed in a circle it means all the vertices of quadrilateral are touching the circle. therefore it is a cyclic quadrilateral and sum of the opposite angles in cyclic quadrilateral is supplementary. suppose if one angle is A then another will be 180 degree - angle A.
Uh ya
opposite angles are supplementary
No. For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees. A parallelogram can be inscribed in a circle if it is a rectangle.
opposite angles in which type of quadrilateral?
Yes, the opposite angles in a regular quadrilateral are equal.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
All supplementary angles do not form a linear pair. The opposite angles of any quadrilateral inscribed in a circle (a cyclic quadrilateral) are supplementary but they are not a linear pair. However, all linear pair are supplementary.
