Question tags are short questions added to the end of statements to confirm information or encourage responses. Key rules for forming question tags include changing the auxiliary verb from positive to negative and vice versa, using 'will you' for imperatives, and 'shall we' for suggestions. Additional rules address cases with no direct auxiliary and the usage of 'has', 'have', or 'had' as main verbs.
