I am trying to solve a problem in which we need to prove that the set of all circles with rational points and radii is homemorphic to the set of all rectangles with vertices at rational points with the length of the diagonals as rational number. I am not able to figure out what the approach should be. Any help or hints to solve the problem would be deeply appreciated.(adsbygoogle = window.adsbygoogle || []).push({});
