Guys while circumscribing a circle in a hexagon , do we have to take its any 2 perpendicular bisectors and do it ? Or do we have to draw 2 diagonals in the hexagon,take its intersecting point and draw a circle ?? I remember my teacher saying not to opt for the 1 one but rather prefer 2 nd method ( diagonal method ) ....
