Which tab in Microsoft Word allows you to look under to change the page orientation?

The page layout tab on the Microsoft word allows you to look under to change the page orientation.
The page layout affects how the content appears. There are two-page layout options in Microsoft word, the landscape which means the page is horizontal and portraits means the page is vertical.

Steps to apply the changes are: select the page layout tab, click the orientation command in the page setup group, click either landscape or portrait to change the page orientation, then the page orientation changes.
