Does pages support RTF format?

That tells you "no."

"If you'd like to work with Rich Text Format (.rtf) documents, you can copy and paste the content into a new Pages document and it will retain its formatting."

how can I convert a pages document to RTF? I don't have that option on my export to bar. Thanks

You can't. As previously discussed in this thread, Pages does not support RTF.
