Pre-image Image D Center of dilation Useful vocabulary for this screen: Pre-image - The original shape or figure. Image - The shape or figure after it makes transformations. Note: If there are 'symbols on the points of a figure, this can be assumed as the image. Center of dilation - A fixed point where all of the other points and lines are extended to create a dilated shape. Similarity - Two or more figures are similar when they have proportional side lengths and congruent angles. Similar figures can be viewed as the pre-image taking rigid transformations and dilation to create the image. d.

Useful vocabulary for this screen:
Pre-image - The original shape or figure.
Image - The shape or figure after it makes
transformations. Note: If there are 'symbols on the
points of a figure, this can be assumed as the image.
Center of dilation - A fixed point where all of the other
points and lines are extended to create a dilated shape.
Similarity - Two or more figures are similar when they
have proportional side lengths and congruent angles.
Similar figures can be viewed as the pre-image taking
rigid transformations and dilation to create the image.
