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.

The opposite angles of a quadrilateral inscribed in a circle are?

The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.


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.


Which property is always true for a quadrilateral inscribed in a circle?

opposite angles are supplementary


Are The Opposite Angles Of A Quadrilateral In A Circumscribed Circle Are Always Supplementary.?

Yes, the opposite angles of a quadrilateral inscribed in a circumscribed circle (cyclic quadrilateral) are always supplementary. This means that the sum of each pair of opposite angles equals 180 degrees. This property arises from the fact that the inscribed angles subtend the same arc, leading to their supplementary relationship. Thus, if one angle measures (x), the opposite angle will measure (180 - x).


Can a parallelogram always be inscribed in a circle?

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.

Do all supplementary angles from a linear pair Are all linear pair supplementary?

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.


Given a quadrilateral inscribed in a circle which pairs are valid opposite angle measures?

Which set of measures describes a quadrilateral that cannot be inscribed in a circle 69 103 111 77 or 52 64 128 116 or 42 64 118 136 or 100 72 80 108?

A quadrilateral can be inscribed in a circle if the opposite angles are supplementary. To determine which set of measures cannot form a cyclic quadrilateral, we calculate the sums of opposite angles for each set. The set of angles 100, 72, 80, and 108 has opposite angle pairs (100 + 80 = 180 and 72 + 108 = 180), which are supplementary. However, the other sets do not all yield supplementary pairs, with 42, 64, 118, and 136 failing this condition. Thus, 42, 64, 118, and 136 describe a quadrilateral that cannot be inscribed in a circle.


The opposite angles of a quadrilateral in a circumscribed circle are always complimentary?

No, they are supplementary.
