Target Line - Plane Line - Line of Flight

[Martee]

my take from pg 150-151 of 6th ed:

1. Line of Flight and Target Line are the same thing
2. Square, Open or Closed
3. See #2

Ah-Ha, see I can't write, for questions 2 and 3 I should have worded it better but your answers do answer the question. What I was asking are each of those the same, but since you stated that they could be Square, Open, or Closed would indicate that they are not one of the same. I will edit my questions.
