How can I copy only one page on iPad pages app?

Solution 1:

open the document and at the top, you see an icon that looks like a page divided into 1/3 and 2/3. See the image below. Tap on that icon and you'll see "Page Thumbnails". Turn that on and then tap on the document. You'll see the thumbnails on the left. Tap on the Thumbnails you want and you'll get an option to copy or edit.
