2. What is a rigid transformation?  A transformation that does not change the size or shape of a figure

3. Preimage and Image  Preimage – a shape that undergoes a motion or transformation  Image – a shape that results from a transformation of a preimage

4. Types of Transformations  Translation  Rotation  Reflection

5. Translation  A transformation in which every point of the preimage is moved the same distance in the same direction  Example

6. Rotation  A transformation in which every point of the preimage is moved by the same angle through a circle centered at a given fixed point known as the center of rotation

7. Reflection  A transformation in which every point of the preimage is moved across a line known as the mirror line so that the mirror is the perpendicular bisector of the segment connecting the point and its image

8. Reflection (cont’d)
