Answer 1

Step-by-step explanation:

please note that the size

Answer 2

Answer:

Let us consider a circle with center O and two equal chords of a circle AB and CD.

We need to prove that ∠AOB=∠COD

In △ AOB and COD,  we have 

AO=CO  (Radius of the circle) 

BO=DO  (Radius of the circle) 

AB=CD  (Equal chords)

By SAS criterion of congruence, we have 

△AOB≅△COD

⇒∠AOB=∠COD
