Imperatives, questions or statements aligned to a clause to get an answer from the listener is called Question Tags.

Usually, tags have an auxiliary verb or a main verb plus a subject, which would usually be a pronoun.  

Question tag turns statements into yes or no questions.

There are two types of questions tags.

The first one has a negative main clause and an affirmative tag or an affirmative main clause and a negative tag.

The second type has an affirmative main clause and an affirmative tag. Statement tag is used to reinforce an affirmative statement.
