Dilations
Draw Dilations A dilation is a similarity transformation that enlarges or reduces a figure proportionally.
Dilations are completed with respect to a center point and a scale factor. Example: Draw the dilation image of ᇞABC with center O and r = 2.Exercises
Use a ruler to draw the image of the figure under a dilation with center S and the scale factor r indicated.
1. r = 2 2. r = ଵ
63. r = 1 4. r = 3
7 6. r = 1

Dilations
Dilations In The Coordinate Plane To find the coordinates of an image after a dilation centered at the origin,
multiply the x- and y-coordinates of each point on the preimage by the scale factor of the dilation, r.
(x, yĺrx, ry)Example: ᇞABC has vertices A(2, 2), B(1, 1), and C(2, 0). Find the image of ᇞABC after a dilation centered at
the origin with a scale factor of 2. Multiply the x- and y-coordinates of each vertex by the scale factor, 2. (x, y) (2x, 2y)
