Rather than rotating the document permanently, you can rotate the document view instead. This allows you to view your document from a different angle without manipulating its layout.
About document view rotation
Being able to rotate the document view is beneficial for a number of applications:

Tablet-assisted design (drawing at angles)
To rotate the document view:
Open the Navigator panel.
Tap on the padlock icon next to the Rotation setting to lock/unlock rotation.
Do one of the following:
Place two fingers on the screen of your device and then rotate them in whichever direction you'd like the document view to turn.
Drag on the Rotation setting to alter the rotation.
Tap on the setting and manually enter a number into the pop-up menu.
To reset the document view back to its original rotation:
Do one of the following:
On the Navigator panel, double-tap the Rotation setting.
