Working with Compositions and Glide Reflections Topic Index | Geometry Index | Regents Exam Prep Center

Answer the following questions dealing with compositions and
glide reflections.

 1. Does this graphic illustrate a glide reflection? Yes No Explanation No. There is no reflection.

 2. Orientation is preserved under a glide reflection. True False Explanation No. The reflection changes the orientation.

 3. Write a rule for the composition of a dilation of scale factor 3 following a translation of 2 units to the right. Choose: Explanation First do the translation of 2 units right (x,y) -> (x+2,y) Then do the dilation factor 3: (x+2,y) -> (3(x+2), 3y) Answer: (3x+6, 3y)

 4. Examine the graph at the left.  Is triangle A"B"C" a glide reflection of triangle ABC? Yes No

 5 Does this paw print illustration depict a glide reflection?Yes No

 6 Which composition of transformations will map ? Choose: (dilations centered at origin)

 7 A triangle has vertices A(3,2), B(4,1) and C(4,3).  What are the coordinates of point B under a glide reflection, ? Choose: (2,-4) (4,0) (4,-2) (-4,2)
