4/15/2011 Geometry Transformations A transformation is the mapping, or movement, of all the points of a figure in a plane according to a common operation. A rigid motion is a transformation of points in space.
Translation • A transformation slides points the same distance and in the same direction The original figure is called the pre-image. The new figure created from the translation is called the image. image pre-image
