  1. 2. A function that changes the position,size,or shape, of a figure or graph
  2. 4. a figure has symmetry if there is a transformation that maps the figure to itself
  3. 7. A stretch changes the shape of a figure by a factor greater than one in one direction
  4. 8. an isometry or rigid motion is a transformation that does not change the size or shape of a figure
  5. 10. a vector is a quantity that has both direction and magnitude
  6. 11. a rotation that turns a figure through an angle of rotation
  7. 12. A compression changes the shape of a figure by a factor greater then 0 and less than 1 in one direction
  8. 14. a transformation maps a preimage determined by set of points in the plane to a corresponding set of points called images
  9. 15. A dilation changes the size of a figure by the same amount in all directions
Down
  1. 1. a figure that can be rotated about its center by an angle of 180 or less so that the image coincides with the preimage
  2. 3. one type of rigid motion is translation or slate
  3. 5. The angle of rotation is the smallest angle of rotation that maps a figure to itself
  4. 6. when translating a figure in a coordinate plane,you can write the translation vector
  5. 9. The center of dilation is the fixed point in the plane that does not change when the dilation is applied
  6. 13. a reflection is a transformation across a line called the line of reflection
