GEO-B1-M05-P006 The Opposite Angle
#6
★★☆☆☆ Level 2 of 5
In cyclic quadrilateral \(ABCD\), it is known that \(\angle A=68^\circ\). Find \(\angle C\).
Opposite angles of a cyclic quadrilateral sum to \(180^\circ\).
Since \(ABCD\) is cyclic, \(\angle A+\angle C=180^\circ\). Therefore \(\angle C=180^\circ-68^\circ=112^\circ\).
A simple task on the sum of opposite angles.
