When you compile a PDF from multiple sources, you might find that some of the pages are sideways or inverted when you try to view them on-screen. Never fear! Acrobat can be used to rotate individual pages within a PDF document.
Select Document > Rotate Pages.
Choose your direction from the drop down box (clockwise 90 degrees, counter-clockwise 90 degrees, 180 degrees).
Choose your page range (all, selection, pages) and set any rotation options if appropriate (page of any orientation, portrait page, landscape pages).
