Question

pq and rs are two equal chords of a circle with centre Such that angle poQ= 70 then angle ors is​

Answer 1

∠ORS  = 55° pq and rs are two equal chords  & ∠POQ= 70°

Step-by-step explanation:

PQ = RS

Let compare Triangle OPQ   & ΔORS

OP  = OR    ( Radius)

OQ = OS     (radius)

PQ = RS

=> OPQ   ≅ ΔORS

=> ∠ROS  = 70°

now OR = OS = (Radius)

=> ∠ORS = ∠OSR

∠ORS + ∠OSR + ∠ROS  = 180°

=> 2 ∠ORS + 70° = 180°

=>  2 ∠ORS  = 110°

=> ∠ORS  = 55°
