# How do you rotate the Cartesian coordinate system?

If a standard right-handed Cartesian coordinate system is used, with the x-axis to the right and the y-axis up, the rotation R(θ) is counterclockwise. If a left-handed Cartesian coordinate system is used, with x directed to the right but y directed down, R(θ) is clockwise.Click to see full answer. Then, what are the formulas for rotation?180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn’t change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b).Subsequently, question is, what are the 4 types of transformations? There are four main types of transformations: translation, rotation, reflection and dilation. Keeping this in consideration, how do you rotate a point about the origin? If you wanted to rotate the point around something other than the origin, you need to first translate the whole system so that the point of rotation is at the origin. Then perform the rotation. And finally, undo the translation.What is the rule for translation?In a translation, every point of the object must be moved in the same direction and for the same distance. When you are performing a translation, the initial object is called the pre-image, and the object after the translation is called the image.
