Please use the forum "Search" feature before asking questions. In this case, "rotate" finds a half dozen threads which already cover this.
Summarizing: use the "bottom-right" swipe gesture to rotate. Note there is a bug which requires you to then "bottom swipe" (up from bottom) as though minimizing your app, then click on it to restore it again. At that point it will be in the rotated orientation.
