Geometry Section 6.7 Perform Similarity Transformations

Dilation A transformation that stretches or shrinks a figure to create a similar figure  Similarity transformation Center of Dilation -fixed point in respect that a figure is enlarged or reduced Scale Factor of a dilation-the ratio of a side length of the image to the corresponding side length of the original figure.

Coordinate Notation for a Dilation Describe a dilation with respect to the origin with the notation (x, y)→(kx, ky) where k is the scale factor. k >1 enlargement 0 < k < 1 reduction
