Lipschitz parametrization of a symmetric convex curve
@ Anton, I came back to the original question, since there is not a counterexample yet. |

Lipschitz parametrization of a symmetric convex curve
@Anton, Did you forget to put $\epsilon \alpha+o(\alpha)$. Remember that I am asking of bi-Lipschitz mappings between curves (not between open domains). |

@Anton: I didn't understand this argument indeed. How do you relate angles with bi-Lipschitz. Maybe it is not quasiconformal at the corrners. |

@Anton. I guess that arc-length parametrization g is the best mapping for part. You can prove that $Lip(g)\le \pi/2 diam(γ)/2$, but this is not that I expect. |

$Lip(f)=1/4 \sqrt{2} \pi$ |

The square in not a counterexample. Namely, assume as we may that the square $|\gamma|=2\pi$. Then by using arc-length parametrization $f: S^1\to \gamma$ we obtain that $Lip(f)=\sqrt{2}{4}\pi$. |

@Sergei I meant that the map should be a homeomorphism, otherwise the question is trivial. Your projection maybe is not onto? |

Lipschitz map of the circle onto a triangle
Then you obtain $L^9$ growth of bi-Lipschitz constant. |

Lipschitz map of the ellipse
The metric from the Euclidean plane is assumed and Mixon has the answer. |
