    Dear friends, The following three angles are obtuse : 1.angle(GIH) G is centroid,I is incenter,H is orthocenter. 2.angle(GIGe) Ge is Gergonne point.

      Dear friends,

      The following three angles are obtuse :

      1.angle(GIH)
      G is centroid,I is incenter,H is orthocenter.

      2.angle(GIGe)
      Ge is Gergonne point.

      3.angle(NaGeH)
      Na is Nagel point.

      For distances we have the following inequalities

      1.OI >=2NI
      N is center of Euler circle,O is circumcenter.
      2.OH<=3OI.
      3.GeNa<=4IK
      K is Lemoine point.
      4.2SpH>=9IGe
      Sp is Spieker point.

      Maybe something useful could be in these
      relations.

      Best regards

      Milorad R.Stevanovic
