  1. Let I is incenter of triangle ABC
    Let BI meet AC at L
    Observe that EBDI is a complete quadrangle so L, F are harmonic conjugate points of A and C.
    Since BL is an internal bisector of angle ABC So BL is external bisectors of angle ABC and FH=FG

  2. this problem need
    1) BF bisector of CBH
    2) IBF = 90
    3) BI // GH
    4) GB = BH
    It is possible in another construcsion included AB > BC
