In the given figure, it is given that chords AB=PQ, ∠AOB=550, and ∠POQ=x0, find x.
55
Here, we are given that AB=PQ
Now, let us consider ΔAOB and ΔPOQ,
Here, AB=PQ [given]
AO=PO= radius of the circle
Similarly, BO=QO= radius of the circle
∴ΔAOB≅ΔPOQ [By SSS congruency]
Hence, ∠POQ=∠AOB=55∘ [C.P.C.T]
