Lesson 6.3 Rotations

Lesson 6.3 Rotations

by Reed Carbone

​Definitions

​Rotation: A rotation is a transformation that turns a figure around a fixed point called the center of rotation.

​

​Angle of Rotation: This is the measurement of the number of degrees the figure rotates. We will rotate 90, 180, 270 and 360 degrees counter clockwise. (Note: if the number is negative your figure will rotate clockwise.)

​Visual:

​Here is what a rotation will look like:
