	Especially contested was Savants' statement that Wiles' proof should be rejected for its use of non-Euclidean geometry. Savant stated that because "the chain of proof is based in hyperbolic (Lobachevskian) geometry", and because squaring the circle is seen as a "famous impossibility" despite being possible in hyperbolic geometry, then "if we reject a hyperbolic method of squaring the circle, we should also reject a hyperbolic proof of Fermat's last theorem."
