### Rotation

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

Rotate 90 degrees counterclockwise

Rotate 180 degrees
Math Rotations

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.

Rotation of figures

How to rotate a figure 90 degrees rotation about a point O using a compass and a protractor.
Geometry Construction: Rotating a Figure by Hand

How to rotate a figure around a fixed point using a compass and protractor.

Rotate "H" 100 degrees counterclockwise around a point P.

### Rotations on the Coordinate Plane

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.
