 Friday, 1/16/2015 is the last day of schedule changes  Monday, 1/19/2015 is a student holiday.  Transformations Unit test 1/27/2015 & 1/28/2015  Today we will continue transformations  Rotations

A rotation is a transformation that turns a figure about (around) a point or a line. The point a figure turns around is called the center of rotation. Basically, rotation means to spin a shape. The center of rotation can be on or outside the shape.

What does a rotation look like? A ROTATION MEANS TO TURN A FIGURE center of rotation

This is another way rotation looks A ROTATION MEANS TO TURN A FIGURE The triangle was rotated around the point. center of rotation

If a shape spins 360 , how far does it spin? 360 

If a shape spins 180 , how far does it spin? 180  Rotating a shape 180  turns a shape upside down.

Describe how the triangle A was transformed to make triangle B AB Describe the translation. Triangle A was rotated right 90 

Describe how the arrow A was transformed to make arrow B Describe the translation. Arrow A was rotated right 180  A B
