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.

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
