Given a set of oriented hyperplanes P=\p1, ..., pk\ in ℝn, define v(P) for any point P∈ℝn as the sum of the signed distances from P to p1,..., pk. We give a simple geometric characterization of P so that v is a constant. The characterization leads to a connection with the Fermat point of k points in ℝn. Finally, we discuss historically the full content of Viviani's theorem.
