![]() We can use the following rules to find the image after 90 °, 18 0 °, 27 0 ° clockwise and counterclockwise rotation. But points, lines, and shapes can be rotates by any point (not just the origin)! When that happens, we need to use our protractor and/or knowledge of rotations to help us find the answer. Rotation transformation is one of the four types of transformations in geometry. The rotation rules above only apply to those being rotated about the origin (the point (0,0)) on the coordinate plane. Study with Quizlet and memorize flashcards containing terms. ![]() When mapping this sequence of rigid motions, what would you do first, second, then third Rotation, Reflection, and Translation. If we compare our coordinate point for triangle ABC before and after the rotation we can see a pattern, check it out below: When rotating 90 degrees clockwise, what formula do you use. To derive our rotation rules, we can take a look at our first example, when we rotated triangle ABC 90º counterclockwise about the origin. Rotation Rules: Where did these rules come from? Yes, it’s memorizing but if you need more options check out numbers 1 and 2 above! A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
