Previous Introduction to Transformations Next Enlargement
  • Rotation is a transformation that rotates a shape around a center point
  • Three pieces of information are needed to perform a rotation: the center of rotation, the direction of turn, and the angle of turn
  • The center of rotation is the point that doesn't move during the rotation
  • The direction of rotation can be clockwise or counterclockwise
  • The angle of turn is the amount of rotation, usually in multiples of 90 degrees
  • To perform a rotation, mark the center of rotation, identify the direction of rotation, and draw the image of the shape after rotation
  • Tracing paper or imagining rectangles from each vertex to the center of rotation can help visualize the rotation
  • The ability to carry out rotation transformations and describe transformations is important
