Terminar can be a transitive verb. But the dictionary also provides this entry for terminar as an intransitive verb:
intransitive verb 2. to end, to finish (acabar) ; to stop, to terminate (tren)
¿cómo termina la historia? -> how does the story end o finish? terminar con -> to put an end to (pobreza, corrupción) **terminar de hacer algo** -> to finish doing something terminar en -> to end in (objeto)
Notice that this intransitive form is used in an expression "to finish doing something" and includes the verb plus "de hacer algo" to express what the subject is finishing doing.
