Please be a little bit more specific. Thank you.

Hi,

hexagon as shown is inscribed in the circle..

each angle of hexagon is 120...

when you join opposite vertices, these are also the diagonals and bisect the angles 120..

this is the reason why all three angles are 60 and teh side of hexa too equals radius =1..

hope it helps
