  2. 2. What vector describes the translation R R’? R R’
  3. 3. Circle the folling statements that are true. <ul><li>A transformation is an isometry </li></ul><ul><li>A rotation is an isometry </li></ul><ul><li>A dilation is an isometry </li></ul>
  4. 4. Circle the figures below that have rotational symmetry
  5. 5. Rectangle SHAM is to be dilated by a scale factor of three, using (0,0) as the center of dilation. What will be the coordinates of A’? S H A M
  6. 6. Triangle SAR is to be translated using the same translation as pentagon SHANO. What will be the location of R’? S A R
  7. 7. Δ ZAC is reflected in line l to obtain quadrilateral ZACA’. What is the most precise name for the quadrilateral? Z A C l
  8. 8. Figure M’O’R’ is the image of figure MOR when reflected in a line. Construct the line of reflection.
  9. 9. What is the smallest angle of rotation needed to map the shape onto itself?
  10. 10. The figure below is a regular hexagon whose center is at the origin. What is the measure of the angle of rotation about the origin if A moves clockwise to the position of A’? A A’
