vocabulary
complete the blanks with the vocabulary word.

1. __________: a change in the position, size, or of a figure.
2. __________: the original figure before a transformation.
3. __________: the figure after a transformation.
4. __________: a transformation that preserves and shape (translations, reflections, rotations).
5. __________: a transformation that slides a figure without turning it.
6. __________: a transformation that flips a figure line (line of reflection).

__________: a transformation that turns a figure a fixed point (center of rotation).
__________: a transformation that enlarges or figure by a scale factor.
if one image can be obtained from another by a sequence of transformations and dilations, the images are __________

Explanation:

1. Transformation is defined as a change in position, size, or shape of a figure.
2. Pre - image is the original figure before transformation.
3. Image is the figure after a transformation.
4. Rigid transformation preserves distance and shape (translations, reflections, rotations).
5. Translation slides a figure without turning it.
6. Reflection flips a figure over a line (line of reflection).
7. Rotation turns a figure around a fixed point (center of rotation).
8. Dilation enlarges or reduces a figure by a scale factor. If one image can be obtained from another by a sequence of transformations and dilations, the images are similar.

Answer:

1. Transformation
2. Pre - image
3. Image
4. Rigid transformation
5. Translation
6. Reflection
7. Rotation
8. Dilation; similar
