The answer depends on exactly what you mean by "using a polygon" to create a tessellation. Can you give us an example of what you were taught about this?

This page talks about what it means to me. Each of the congruent figures is thought of as a modification of a simple polygon, which maybe a rectangle, or any of several other types. What you have done recognizes some of the symmetries of the pattern, but not all, and is not tied to the individual figures within it. So I don't think it is what is intended.

I've worked out an answer to the problem, but it will only be useful if you put in the time to understand what you have been taught, and show your attempt. Once you've done that, I can give you a hint for what I did, or suggest a change to your own idea.
