"Transformations - Dilations

Dilations-

A dilated figure can change in ONLY size and location NOT in shape ! Do you have a camera? Well if you do, notice that when you zoom into a photo the picture gets bigger, the size changes, and the location. Zooming into a photo can relate to dilations because when a dilate a figure it changes in size,and location. The way this works is by using a scale factor. A scale factor is a number used as a multiplier in scaling. If a figure undergoes a dilation with a scale factor of 1.5 it will get bigger because they way the scale factor works is "If the scale factors are greater than one, the figure will get larger. If the scale factors are less than one the figure will get smaller.'' For example, if the scale factor is 0.5 the figure will get smaller because 0.5 is smaller than one.
Dilations are different from translations because a translation only slides; it slides left, right, up or down the shape does change. However, in dilations the figure does change size and location. Multiplying by 1/3 is the same as dividing by 3 because since the inverse operation of multiplying is dividing, you can divide the number by the denominator.
