Sideways scans are a rotate job, not an edit job
Rotate PDF pages comes up the moment a scanner or a camera saves a landscape page into a portrait file. You should not need a drawing tool. You need the page turned 90 degrees, and you need the rest of the packet left alone if only one page is wrong.
ViaPDF’s Rotate tool does both. Tap a page to turn it 90° clockwise, and a small badge shows 90°, 180°, or 270°. The All pages bar rotates every page left or right.

If the scan has wide white edges, crop the margins once it is upright. If the words on the scan need to be copied, use OCR after the page is upright.
