Problem Statement

A parallelogram ABCDABCD is split by the diagonal BDBD into two equal triangles. A regular hexagon is inscribed into the triangle ABDABD so that two of its consecutive sides lie on ABAB and ADAD and one of its vertices lies on BDBD. Another regular hexagon is inscribed into the triangle CBDCBD{} so that two of its consecutive vertices lie on CBCB and CDCD and one of its sides lies on BDBD. Which of the hexagons is bigger?
