Chapter 9 Transformations

Chapter 9 Transformations. Objective: Students will recognize and draw reflections, translations, dilations, and rotations. Transformations. A transformation maps an initial figure, called the preimage , onto a final figure, called the image . Four main transformations Reflection

Section 7-3

Section 7-3. Compositions of Transformations. When you apply one transformation to a figure and then apply another transformation on its image, the result is called a composition. A triangle is drawn with vertices: (0,0), (4,0) and (2,5). Two translations are performed on the triangle.

9.3 Rotations

9.3 Rotations. Rotations. A rotation is a transformation that turns every point of the preimage through a specified angle and direction. The fixed point is the center of rotation . The degree of the turn is the angle of rotation. Rotations Using Reflections.
