head page in previous chapter

Question

Good Afternoon I am writting my thesis.

In chapters "acknowledgments" , "abstract" etc , I want a head page. How I can put this?

I had a head page in others chapters (after list of tables). I would like the number page (in roman format) in left side (even pages) and right side (odd pages).
