Purpose of Part VII :

• In this Part VII of the paper here ,
  • we shall identify for each-and-every triangle other than the Equilateral Triangle ,
    • an invariant line associated with that particular triangle .

• For our discussion purpose here in Part VII and beyond ,
  • we shall name this line the { FENG-Line } ,

    with :

    • [ FENG ] being the pronunciation of the author's surname { FUNG } in Chinese Putonghua .

  And we take special note here that the { FENG-Line } is not the same as the Euler Line ,

  • unless the triangle itself is an { isosceles triangle }.
