Rotations and reflections in two dimensions

In two-dimensional geometry, rotations and reflections are two types of transformations that can change the position or orientation of a figure without altering its shape or size. ### Rotations A rotation involves turning a figure about a fixed point called the center of rotation. The rotation is described by an angle (in degrees or radians) and a direction (usually clockwise or counterclockwise): 1. **Center of Rotation**: The fixed point about which the figure is rotated.
