Transformations - Dilations

The figure can grow larger, zooming out or the figure can grow smaller, zooming in. Zooming relates to dilations because a dilated figure will either get larger or smaller. If the scale is greater than (1) the figure will get larger,so for 0.5 the figure will get smaller, because is lower than (1). Dilations are differ from translations because a dilation is when you change a figure's size without changing in shape, but in the other hand translation is sliding a figure to a differ location. Multiplying by 1/3 is the same as dividing by 3 because,just as dividing by 3 is the same as multiplying by 1/3 and, dividing by 1/3 is the same as multiplying by 3, to divide by a fraction is the same as multiplying by its reciprocal.
