Example Questions
Example Question #51 : Geometry
What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided?
A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:
Notice that both the length and the width of the rectangle is a fourth of the size in the purple rectangle, from the blue rectangle; thus the scale of the dilation is
