2.  T RANSLATION : Sliding a figure from one position to another without turning it.

3.  R EFLECTION : Flipping a figure over a line

4.  R OTATION : Turning a figure around a fixed point.

5.  Identify each motion as a translation, reflection, or rotation rotationreflectiontranslation

6.  P REIMAGE : The points on a figure before a translation  M APPING : Pairing points from a preimage to its translated image. Each point on the original figure is called a preimage. Its matching point on the corresponding figure is called its image.

7.  The symbol  is used to indicate mapping. On the previous slide, ABC  DEF. When naming triangles, the order of the vertices indicates the corresponding points.  The mapping is called a TRANSFORMATION PreimageImagePreimageImage A  DAB  DE B  EBC  EF C  FAC  DF

8.  In the figure XYZ  ABC by a reflection › Name the image of X.  XYZ  ABC  X corresponds to A › Name the side the corresponds to AB.  XYZ  ABC  XY corresponds to AB
