3. Reflectional Symmetry • A reflection is an isometry, which means the original and image are congruent, that can be described as a "flip". To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite.

11. Transformations Overview Today’s Focus To *Reflection Other Transformations *Rotation *Translation *Dilation

12. Rotation A rotation is a transformation in which a figure is turned about a fixed point. The fixed point is the center of rotation. Rays drawn from the center of rotation to a point and its image form an angle called the angle of rotation.

13. Rotations can be clockwise or counterclockwise. • Clockwise rotation • Counterclockwise rotation

14. Translation • A transformation that maps all points of a figure the same distance in the same direction.

15. Reflectional Symmetry Constructing a Reflection • A reflection can be described as a "flip". To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. • One to One Mapping about a line of symmety.
