Summary: Include = reuse of functionality. Extends = new and/or optional functionality. You will most often find the 2nd usage (i.e. optional functionality) of extends, because if functionality is not optional, then most times it is built into the use case itself, rather than being an extension. Include Use Case - The include use case never stand alone. When an actor initiates any base use case then base use case executes included use case. Extend Use Case - The extending use case may stand alone, but under certain conditions, its behavior may be extended by behavior of another use case.

Include is a relationship in use case diagrams that represents the inclusion of one use case within another. It is used to show that the behavior of the included use case is always performed in the context of the including use case. In other words, the included use case is a necessary step or sub-functionality of the including use case. Extending Use Case Diagrams A Practical Guide
