Key Concepts

Rotation Transformation

A rotation transformation in geometry is a movement of a figure around a fixed point, known as the center of rotation, by a specific angle in a specified direction. This concept is fundamental in understanding how figures change position while retaining their shape and size.

Center of Rotation

The center of rotation is the fixed point about which all points of a figure are rotated. No matter how many times the figure is rotated, the center remains in the same position and serves as the pivot for the movement.

Angle of Rotation

The angle of rotation is the measure of the turn applied to a figure relative to its center of rotation. It determines how far each point of the figure travels along its circular path and is usually measured in degrees or radians.

Image under Transformation

The image under a transformation is the new position of a point or figure after the transformation has been applied. In the context of rotation, the image of a point is its specific location after being rotated by the given angle about the rotation center.
