Continuity editing:

Continuity editing is one scene leads on into another. This is done through several  ways:

Eye-line match: This is when the shot has the character looking at something, then the next shot is what they are looking at.. For example in game of thrones, In the prolouge, A ride looking at some tree's.

Match-on-action: A match-on-action shot is when a character starts an action in one shot, such as opening door, and continuing it in the next shot, with them finishing opening the door, filmed from a different angle.

Graphic match: This is when 2 shots are linked by similarly shaped items, such as in Indiana Jones, where the Paramount logo graphic matches with a different mountain.

The 180 degree rule: This is when 2 characters or objects should  keep the same left/right relationships, as when the camera turns 180 degree, it looks like have swapped places, even if they haven't moved.

The shot reverse: This is when the camera alternates between two people, usually while filming an argument. An example is in the news when they use this to show a news reader nodding while they edit interviewer answers.
