Transformations: Rotations on a Coordinate Plane Meet TED

Using Rotations A rotation is a transformation in which a figure is turned about a fixed point. The fixed point is the center of rotation. Rays drawn from.

Review: A TRANSFORMATION is when a figure or point is moved to a new position in a coordinate plane. This move may include a change in size as.

Blue Day – 1/16/2015 Gold Day – 1/20/2015

 Friday, 1/16/2015 is the last day of schedule changes  Monday, 1/19/2015 is a student holiday.  Transformations Unit test 1/29/2015 & 1/30/2015  Today we will continue transformations  Rotations

 Rotations are Counterclockwise unless otherwise stated  Rotating 90° Counterclockwise or 270° clockwise  Switch x and y, then  Change sign of new x  Ex: (2,-4) rotated becomes (4,2)  Rotating 180° Counterclockwise or 180° clockwise  Change signs of x and y only  Ex: (-2,4) rotated becomes (2,-4)  Rotating 270° Counterclockwise or 90° clockwise  Switch x and y, then  Change sign of new y  Ex: (2, 4) rotated becomes (4, -2)
