Opposite angles two angles of a quadrilateral which are not adjacent angles are known as opposite angles of the quadrilateral .

Consecutive Angles and opposite angles

Adjacent angles two angles of a quadrilateral are called adjacent angles if they have a common side as arm.

Adjacent angles two angles of a quadrilateral are called adjacent angles if they have a common side as an arm.

The angles of a quadrilateral are in the ratio 3:4:5:6 . The respective angles of the quadrilateral are
