If PQRS is a cyclic quadrilateral and PQ is diameter, find the value of ∠PQS.
A. 45°
B. 110°
C. 20°
D. 80°
Answer:C
If PQRS is a cyclic quadrilateral and PQ is diameter, find the value of ∠PQS.
A. 45° B. 110° C. 20° D. 80°
Explanation: Since PQRS is a cyclic quadrilateral, Sum of either pair of opposite angles of cyclic quadrilateral is 180°. ⇒ ∠QRS + ∠QPS = 180°
