Question

In the figure quadrilateral pqrs is cyclic. side pq=`side rq. psr=110 degree. find 1) measure of angle pqr 2)m(arc pqr) 3)m(arc qr)

Answer 1

Answer:

1) angle psq = angle pqr .......... ( opposite angles of a cyclic quadrilateral are equal )

therefore , angle pqr = 110 degree

2) m( arc pqr ) = 1/2 × angle psr

= 1/2 × 110

= 55 degree

3) sorry bt it's not possible to find m( arc qr ) nd if someone can so plzz help for third ans....
