Aim: How do we graph Dilation's?

Dilation:

-Dilation is the type of transformation that causes an image to stretch or shrink in proportion to its original size.

Scale Factor:
-The ratio by which the image stretches or shrinks is known as the scale factor.
-If the scale factor is >1, then the image is enlarged
-If the scale factor is >0 and <1, then the image will shrink

PROBLEM:  Draw the dilation image of rectangle EFGH with the center of  dilation at point E and a scale factor of 1/2. OBSERVE: Point E and its image are the same.  It is important to observe the distance from the center of the dilation, E, to the other points of the figure.  Notice EF = 6 and E'F' = 3. HINT:  Be sure to measure distances for this problem.
