A is mid point of chord PQ

B is mid point of chord RS

in the figure chord PQ is parallel to chord RS thus ,

Angle OAQ congruent Angle OBS......(perpendicular drawn from Central to chord bisect the chord so,both angles are 90°).....eq (1)

length of OA congruent length of OB....( PQ parallel PS this distance between center to mid point of chord is equal )......eq- (2)

OQ congruent OS....(radii of same circle )...eq (3)
