Transformation Games and Activities
A rotation (or turn) is a transformation that turns a line or a shape around a fixed point. This point is called the center of rotation. We usually measure the number of degrees of rotation of a shape in a counterclockwise direction.
Introduction to Rotation
Rotate 90 degrees clockwise
90 degrees counterclockwise
Rotate 180 degrees
Students learn that when a figure is turned to a new position, the transformation is called a rotation.
Estimate the number of degrees and state the direction in which the following figure has been rotated.

Transformations - Rotate 90 degrees
Rotating a polygon clockwise 90 degrees around the origin.
Step 1: For a 90 degree rotation around the origin, switch the x, y values of each ordered pair for the location of the new point.
Step 2: After you have your new ordered pairs, plot each point.
Rotate 180 Degrees Around The Origin
This tutorial shows why all signs of an ordered pair of an object become opposite when rotating that object 180 degrees around the origin.
