Answer 2

He isn't very friendly, is he ? is the tag question of the given statement.

• A tag question works a bit like your tags in your posts on social media platforms. It makes the person aware that you are being questioned or you are being referred to.
• Tag question converts the statement into a question. It is a mini-question attached to any given statement.
• Like in this case, the question "is he?" is being asked.

So, the right way to write a tag question is to put a comma after the statement and use the verb with the subject.
