Problem Statement

Find inside the triangle ABCABC, points GG and HH for which, respectively, the geometric mean and the harmonic mean of the distances to the sides of the triangle acquire maximum values. In which cases is the segment GHGH parallel to one of the sides of the triangle? Find the length of such a segment GHGH.
