Abstract:We give a necessary and sufficient quantitative geometric condition for an unbounded set A ? Rn to have the following property with a given c > 0: For every ε ≥ 0 and for every map f: A → Rn such that ></img>                              </span>, there is an isometry T: A → R<sup>n</sup> such that ¦Tx?fx¦ ≤ cε for all x ∈ A.</td>
