Rule for 90 degree rotation geometry3/21/2024 Identify whether or not a shape can be mapped onto itself using rotational symmetry.The point of rotation can be inside or outside of the figure. ![]() A rotation is a type of transformation that moves a figure around a central rotation point, called the point of rotation. (Note: 'Degree' is also used for Temperature, but here we talk about Angles) The Degree Symbol ° We use a little circle ° following the number to mean degrees. In this lesson we’ll look at how the rotation of a figure in a coordinate plane determines where it’s located. Some of the most useful rules to memorize are the transformations of common angles. There are 360 degrees in one Full Rotation (one complete circle around).
