Transformations - Dilation's
A dilated figure does not change in shape or location, however it does change in size. It will either get larger or smaller. When we zoom into a photo, it gets bigger and that does relate to dilation because the figure can get larger. If a figure undergoes dilation with a scale factor of 1.5 the figure will get bigger, and if the scale factor is 0.5, the figure will get smaller because when the scale factor is greater than 1, the figure gets larger and when the scale factor is less than 1, the figure will get smaller. Dilation differ from translations because translation is when you slide the figure to a different location and for dilation, the figure will either get smaller or larger. Moreover in all dilation's, the origin will be the center. Multiplying 1/3 is the same as dividing by 3 because if u divide the number by three then u get the same as if you were to multiply. For example, 1/3 x 6 = 2 and 6 divided by 2 = 3.
