In 1996, N. Chevallier proved a beautiful lemma which connects Diophantine
approximation and multidimensional generalizations of the famous three distance
theorem. Using this lemma we show how known results about the multidimensional
three distance theorem can be deduced from certain known results dealing with the
best Diophantine approximations. Also we obtain some new results about the liminf
version of the problem. Beside this, we discuss the inverse problem: how results
about the multidimensional three distance theorem can be applied to study best
Diophantine approximations.
