How can you change the page orientation in a document?

Changing the page orientation in a document can be effectively done by accessing the 'Page Layout' tab, where options for both 'Portrait' and 'Landscape' orientations are readily available. This method allows you to easily switch between vertical and horizontal layouts, catering to different types of content. The 'Page Layout' tab is specifically designed to manage overall design elements of the document, making it logical to include page orientation settings there.

This option directly addresses the task and presents a straightforward approach, allowing users to visually see their choices and apply them accordingly. Other methods, like accessing 'File' and 'Page Setup,' may also lead to orientation changes but are less direct than the streamlined process offered in the 'Page Layout' section. Adjusting the margins impacts the layout but does not change the orientation, while keyboard shortcuts may not be universally applicable across all software, making them a less reliable choice for all users.
