Isn't every n-gon inscribed in a given circle constructible?

Can't you just construct a line that is 6 times the radius of the circle. Then n-sect the line and use the length of the section as the side length of your n-gon?

If you do 360/n then draw radii separated by angle 360/n then connect the ends you have your n-gon

"Constructible" usually means by ruler and compass. To get an arbitrary angle you need a protractor.
