Just "I turned it around" (as Mitch suggested) sounds nice but I still have a nagging suspicion that in some contexts people might not be sure which way you turned it. "I turned it upside-down so that its left side is now on the right" or "I turned it around so that its left side is now on the right". What is the best thing to say? I think it depends to some extent on what is plausible in your context (is the object so heavy that it can't be turned about a horizontal axis even though it can be slid and turned around a vertical axis?).Īnyway if the context doesn't resolve the ambiguity, I'd favour being explicit even if that means a lot of words, e.g. Even if your listener understood that the side that used to be on the left is now on the right and vice versa, you haven't said whether you turned it around a vertical axis or about a front-back axis. If you need your listener to know how you turned the thing (or which way up it is now), you will need to make that clear - and your suggested "leftside right" fails to make it clear. Note that "flipping an object upside-down" typically involves flipping it about planes that are perpendicular to a vertical axis and another unspecified axis, and "flipping the object around" would involve flipping it about planes perpendicular to both front-to-back and left-to-right axes, while flipping top-to-bottom, left-to-right, or front-to-back would only involve reflection about a single plane.Īs Hot Licks points out, you could - the trouble is, people wouldn't understand you. Such a move is generally called "turning it around" or perhaps "flipping it around".įor operations which flip an object around a single axis only (typically only applicable to operations on a computer, images, or other "virtual" objects), one would typically say the object was flipped top-to-bottom (not upside-down!), left-to-right, or front-to-back. Rotating a box 180 degrees around a vertical axis will flip it left-to-right and front-to-back. ![]() It wouldn't generally matter whether the parts that had been in front stay in front, or the parts that had been on the left stay on the left, or neither, so there's no brief term that makes such distinctions. ![]() What will matter is that the parts of the object that were oriented up are now oriented down, and vice versa. But startups promising fully driverless cars are still raising money. In most cases where one rotates an object 180 degrees about a horizontal axis, it won't matter which horizontal axis one is using. Autonomous vehicles were supposed to be right around the corner but now seem decades or more away.
