Drag and drop the definition to the correct words/answer choices i provided

1. A figure in the plane has this if the figure can be mapped onto itself by a rotation of 180 degrees or less. What is it?
2. A type of composite or combination transformation of a reflection over a line followed by a translation or vice versa. What is it?

3. the operation that maps, or moves, a preimage onto an image. What is it?

4. A line that a figure in the plane has if the figure can be mapped onto itself by a reflection in the line. What is it?

5. Also known as the angle of rotation; the measure of degrees that a figure is rotated about a fixed point. What is it?

6. a type of transformation that maps every 2 point P and Q in the plane to points P' and Q' so that PP'=QQ', PP' is parallel to QQ', or PP' and QQ' are collinear

7. a tranformation that preserves lengths; aka rigid transformation

8. a type of transformation in which a figure is turned about a fixed point

9. motion that proceeds in the same direction as the hands of a clock, from top right, down, then left, back to the top; in math it is in the negative degree direction.

10. a dilation tranformation in which the scale factor is more than 1 which causes the image to be larger, stretched, or expanded, yet is similar (same shape, different size) to the original preimage

11. the new figure that results from the transformation of a figure in a plane

12. a dilation with a scale factor less than 1 which reduces the size of the original figure

13. a line that acts as a mirror and reflects an image for a transformation

14. the original figure in the transformation of a figure in a plane.

15. a type of transformation, with center C and scale factor k, that maps every point P in the plane to a point P'

16. the k or the multiplier of a dilation

your answer choices are:
line of symmetry
reflection
rotation
rotation symmetry
transformation
translation
isometry
dilation
pre image
image
shrink
line of reflection
degree of rotation
clockwise
scale factor
translation
enlargement/expansion

(because there are 2 translations, that means there are 2 definitions of that word that have the same word.)

Here are the definitions matched to the correct answer choices:

  1. A figure in the plane has this if the figure can be mapped onto itself by a rotation of 180 degrees or less. What is it?

    • rotation symmetry

  2. A type of composite or combination transformation of a reflection over a line followed by a translation or vice versa. What is it?

    • glide reflection (This term isn't originally listed among the answers, so it's assumed to be intended.)

  3. The operation that maps, or moves, a preimage onto an image. What is it?

    • transformation

  4. A line that a figure in the plane has if the figure can be mapped onto itself by a reflection in the line. What is it?

    • line of symmetry

  5. Also known as the angle of rotation; the measure of degrees that a figure is rotated about a fixed point. What is it?

    • degree of rotation

  6. A type of transformation that maps every 2 point P and Q in the plane to points P' and Q' so that PP'=QQ', PP' is parallel to QQ', or PP' and QQ' are collinear. What is it?

    • translation

  7. A transformation that preserves lengths; aka rigid transformation. What is it?

    • isometry

  8. A type of transformation in which a figure is turned about a fixed point. What is it?

    • rotation

  9. Motion that proceeds in the same direction as the hands of a clock, from top right, down, then left, back to the top; in math it is in the negative degree direction. What is it?

    • clockwise

  10. A dilation transformation in which the scale factor is more than 1 which causes the image to be larger, stretched, or expanded, yet is similar (same shape, different size) to the original preimage. What is it?

  • enlargement/expansion
  1. The new figure that results from the transformation of a figure in a plane. What is it?
  • image
  1. A dilation with a scale factor less than 1 which reduces the size of the original figure. What is it?
  • shrink
  1. A line that acts as a mirror and reflects an image for a transformation. What is it?
  • line of reflection
  1. The original figure in the transformation of a figure in a plane. What is it?
  • pre image
  1. A type of transformation, with center C and scale factor k, that maps every point P in the plane to a point P'. What is it?
  • dilation
  1. The k or the multiplier of a dilation. What is it?
  • scale factor

Please make sure to replace "glide reflection" with the correct term if it should be found in the list. If not, the list seems to cover most of the common transformation terms comprehensively.
