    Thank you! But why arc CD and arc AB length should add to 2 PI? Or why does the angle COD times two is 2PI if that’s what you meant?

      Point (5) is not about the arcs’ lengths. It’s about the angle they create with the center.

      Also, I never said that COD * 2 = 2π. I said (inner COD) + (outer COD) = 2π rads
