Square inherits from Rectangle. In OOML's this is describe as <pre> Rectangle <-- Square </pre> or more precisely in UML specifically to classes <pre> Rectangle <|-- Square </pre> (???) Why are the inheritance directions opposite from traditional UML directions? Square inherits from Rectangle. In OOML’s this is describe as 
    Rectangle <-- Square

or more precisely in UML specifically to classes

    Rectangle <|-- Square

The key benefit of (public) inheritance is not that it allows you to reuse parts of some existing class, but that it allows you to write new code that is used/reused by existing code, through polymorphism :) In this sense, it is usually wrong to "hide features you do not want", since it means that your derived class would no longer be Liskov substitutable for the base class.
