It finds an approximation of pi by determining the length of the perimeter of a polygon inscribed ... determines the length of a side of each triangle, relative to the diameter, based on the ...
More simply, the angle at the centre is double the angle at the circumference. Angle OGK (\(x\)) = angle OKG because triangle GOK is also isosceles. Lengths OK and OG are also both radii.
