In our preliminary we had to use 3 important things.

1st - 180 degrees rule

 It’s actually a very straight forward convention and helps you to create flowing cut sequences when shooting with a single camera, but you want to create the impression that there are more cameras shooting the scene so that the viewer sees a cut sequence that flows naturally. This means that you will have to direct the actors or contributors to repeat the action over and over again while you shoot the action from different camera positions to get enough scene coverage.

2nd- shot reverse shot

A film technique wherein one character is shown looking (often off-screen) at another character, and then the other character is shown looking "back" at the first character. Since the characters are shown facing in opposite directions, the viewer unconciously assumes that they are looking at each other.
3rd-match on action

is a cut in film editing between either two different objects, two different spaces, or two different compositions in which an object in the two shots graphically match, often helping to establish a strong continuity of action and linking the two shots metaphorically.(Used this information from wikipedia)
