How to say: "at three different sides of the room " I want to tell a joke where the teacher places three students at three different sides of the room. I tried like this, but apparently it was wrong:


  老師讓他們分散在房間的三方。


Can you offer any suggestions? Also things like "place them apart from each other " might help.
