Step-by-step explanation:
Given : OA.OB = OC.OD
To prove : angle A = angle C and angle B = angle D
Proof :
OA . OB = OC . OD. ( Given)
So, OA = OB. ( 1 )
OC. OD
In ∆ AOD & ∆ COB,
OA = OB. ( ↑1 )
OC. OD
Angle AOD = Angle COB ( Vertically opposite angle )
∆ AOD ~ ∆ COB. ( SAS criterion )
Hence,
angle A = angle C
angle B = angle D
