How do you dilate a shape in math?

Answer 1

To dilate a shape in math, you need a center of dilation and a scale factor. The center of dilation is a fixed point from which all other points of the shape will move. The scale factor determines how much the shape enlarges or shrinks; for example, a scale factor greater than 1 enlarges the shape, while a factor between 0 and 1 reduces it. To find the coordinates of the dilated shape, multiply the distance of each point from the center by the scale factor and then apply that to the center's coordinates.
