Across
  1. 3. a figure that can be rotated about its center by an angle of 180 degrees or less so that the image coincides with the preimage
  2. 5. the fixed point in the plane that does not change when the dilation is applied
  3. 8. something that maps a transformation
  4. 9. changes the shape of a figure by factor greater than 1 in one direction
  5. 12. changes the shape of a figure by a factor greater than 0 and less than 1 in one direction
  6. 14. a quantity that has both direction and magnitude
  7. 15. changes the size of a figure by the same amount in all directions
  8. 16. a transformation that maps the figure to itself
  9. 17. a rigid motion that turns a figure through an angle of rotation about a point and its image that are the same distance from a point
  10. 18. divides a plane figure into two congruent, reflected halves
Down
  1. 1. a function that changes the position, size, or shape of a figure or graph
  2. 2. a transformation that does not change the size or shape of a figure
  3. 4. the perpendicular bisector of each segment joining each point and its image
  4. 6. the smallest angle of rotation that maps a figure to itself
  5. 7. has this if it can be reflected over a line so that the image coincides with the preimage
  6. 10. used when translating a figure in a coordinate plane
  7. 11. a transformation that maps every point of a figure or graph the same distance in the same direction
  8. 13. determined by set of points in the plane to a corresponding set of points
  9. 17. a transformation across a line
