Question

in the figure, if, AB = AC and OB = OC, then angle ABO/angle OCA=​

Answer 1

Answer:

Step-by-step explanation:

In ΔABC

AB=AC (given)

⇒∠ABC=∠ACB (since angles opposite to equal sides are equal) ---(i)

In ΔOBC

OB=OC (given)

⇒∠OBC=∠OCB (as angles opposite to equal sides are equal) ---(ii)

subtracting (ii)from (i)

∠ABC−∠OBC=∠ACB−∠OCB

⇒∠ABO=∠ACO
