Question

] If chord AB = chord CD then arc AB = arc CD . Which of the following theorem is used in proving the above statement *
​

Answer 1

Answer:

hope it helps ☺️

Explanation:

Given : chord AB ≃ chord CD.

⇒ length (arc AB minor) = length (arc CD minor)

⇒ (arc AC) + (arc CB) = (arc CB) + (arc BD)

⇒ length of arc (AC) = length of arc (BD)

⇒ (arc AC) ≅ (arc BD)
