    soit str// ou confondu
    s confondu A appartient d2
    remplace equation para par A
    
      -t existe d1 d2 confondue
      -t existe pas

    soit secantes ou nncoplanai
    resous equa para egales
      - t et k existe pas 
      d1 et d2 sont non coplanaires
      - t et k existe d1 et d2 sont
