Press the Home button, which is the circular button at the bottom of the iPad's screen, to do so. This will ensure that you can rotate your iPad's screen orientation without worrying about an app's preferences interfering. You want to make sure that your iPad is physically rotated to the orientation that you want to use, and that the screen has rotated to fit that orientation.  There are two screen orientations available: Portrait, which is the vertical orientation, and Landscape, which is the horizontal orientation.  Landscape is best for watching videos in full-screen mode or typing into a document, while Portrait is ideal for reading articles or browsing websites. Place your finger just below the bottom edge of the screen, then swipe upward. You should see the screen blue, and several icons should pop up on the screen. You may have to try this a couple of times before the Control Center will appear. It's a black-and-white image of a padlock with an arrow encircling it, found on the right side of the screen. Tapping it will cause the padlock to turn red and the surrounding area to turn white, signifying that the screen is locked into place. Doing so will close the Control Center. Your iPad's screen should now be locked into your preferred orientation.  You can unlock the orientation at any time by re-opening the Control Center and tapping the red-and-white "Lock" icon. Some apps don't support different orientations; for example, Minecraft PE necessitates landscape orientation, while apps like Instagram for iPhone will only appear in portrait mode.
