Rotations in the Coordinate Plane
- Anthony DiLaura
Explore the affect rotatoins have on the coordinates of an image in the coordinate plane.
Drag the slider to change the angle of rotation around the origin. Observe the relationship between the preimage and image coordinates. Generalize a rule that determines this relationship for a 90, 180, and 270 degree rotation. Generalize: A coordinate (x,y) that rotates 90 degrees will now have the coordinate? A coordinate (x,y) that rotates 180 degrees will now have the coordinate? A coordinate (x,y) that rotates 270 degree will now have the coordinate? What about a coordinate (-x, y) that is rotated 180 degrees what will it's new coordinate be? Think you got it?
