The dilation formula expresses the relationship between the coordinates of the vertices of the original figure and its dilated image. Given a point $(x, y)$ and a center of dilation $(h, k)$ with a scale factor of r, the coordinates of the dilated point $(x’, y’)$ can be found using the following formulas:
Dilation is the process of resizing an object by a certain scale factor. In geometry shapes can be dilated by a scale up or a scale down factor. Learn what is dilation in geometry, definition, how to calculate scale factor and some solved examples.
A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller).
Dilations make a shape bigger or smaller. A scale factor tells us how much to multiply by the side lengths to change the size. The scale factor is the ratio of the side length in the new shape (image) to the side length in the corresponding side in the original shape (pre-image).

In mathematics, dilation is a type of transformation in which the size of a shape or geometric figure is changed, but the relative proportions and shape remain the same. The quadrilateral and cube above are dilated to produce smaller versions of the respective shapes.
Dilation in mathematics is used in geometry to enlarge or shrink two-dimensional and three-dimensional shapes while preserving their proportions. For example, a square with sides of 4 units can be dilated to a square with sides of 40 units, but its shape remains unchanged.
