Name _____________________________________ Class _____________ Date ____________ Alternative Assessment Chapter 9 Form C TASK 1 A flea is 0.2 cm long. As it walks across the glass surface of an overhead projector, its image on the screen appears to be 4 cm long. What is the scale factor of the dilation? If the flea jumps 10 cm across the glass surface, how far does its image jump across the screen? Explain your reasoning. TASK 2 Create a tessellation that has only translational and rotational symmetry. Draw a figure showing at least four rows and four columns of your tessellation. Name _____________________________________ Class _____________ Date ____________ Alternative Assessment(continued) Chapter 9 Form C TASK 3 In the real world, not all transformations are always possible. For example, if you drive a car around town, what types of transformations does the car undergo? What types can it not undergo? Explain. TASK 4 Draw a quadrilateral in the coordinate plane at the right. Show the figure undergoing the five transformations you have studied in this chapter. Use different coordinate planes for each transformation. List the lines of reflection, the vectors of translation, the degrees of rotation, and the scale factor next to the corresponding transformation. a. translation b. dilation c. reflection d. glide reflection e. rotation
