It is shown that any pair of regular triangulations is connected by a path along which none of their common faces are destroyed. As a consequence, we obtain the connectivity of the flip-graph of regular triangulations that share the same vertex set.Regular triangulationsFlip-graphSecondary polytopeSecondary fantext::journal::journal article::research article
