A rhetorical question is a figure of speech in the form of a question, which are not asked to get answers but to present a point more effectively.
Examples:
If you are in trouble your teacher might ask you questions, and they want you to think about it... if you are sensible and they are angry then the best thing to do is not answer and look down... also an example might be if you just want people to think about the question.
It is not just teachers who use rhetorical questions!
