Across
  1. 2. / A transformation that turns every point of a pre image. The pre image is a specified angle and direction about a fixed point
  2. 5. / you can move the entire design by either rotation, reflection, or translation, and the design appears unchanged.
  3. 8. /a transformation that moves all points of a figure. the points move all in the same distance in the same direction
  4. 10. /a line that passes through two other lines. the two other lines are parallel to each other.
  5. 11. / a composition of a translation and a reflection. on a parallel line it moves to the direction of the translation
  6. 12. / A transformation that is congruent
  7. 14. / the line that is equidistant from the preimage and image points
  8. 15. /The ratio of a length on an image to a corresponding length on the pre image.
Down
  1. 1. / transformation that preserves distance and angle measure. Reflections, rotations, translations, and glide reflections are all examples
  2. 3. / The figure after the transformation
  3. 4. / exists when a figure is built around a single point called the center of the figure
  4. 6. /an object that looks the same after a certain amount of rotation
  5. 7. / has the same or opposite direction
  6. 9. / The original figure
  7. 13. / The point from which dilations are performed.
  8. 15. /The ratio of the lengths of two corresponding sides. it has two similar polygons or two similar solids.
  9. 16. /a plane, mapping for which each point has exactly one image. each image point has exactly one pre image point. change in position, size or shape of a geometric figure
  10. 17. /A transformation representing a flip of the figure over a point
  11. 18. / A transformation determined by a center point. a figure by reducing or enlarging it with a scale factor
  12. 19. / A line that can be drawn through a plane . a figure that can be the reflection image of the figure on the opposite side
