This is the converse of the previous theorem
Note that is given theorem PQR= AMON, then
APQRAMON (Why?)
Is PROM?
the figure. if AB=CD and ZAOB=90° find ZCOD
inns nnd GORS= 48°​

Answer 1

Answer:

Step-by-step explanation:

To Prove --- Chord AB = Chord CD .

Proof -- In △AOB and △COD

AO = CO [radii of same circle]

BO = DO [radii of same circle]

∠AOB = ∠COD [given]

⇒ △AOB ≅ △COD [by SAS test]

⇒ Chord AB = Chord CD
