Scale Factor Dilation Formula
The following formula is used to calculate the scale factor dilation of an image or shape.
SF = X2/X1 = Y2/Y1
- Where SF is the scale factor dilation
- X2 and Y2 are the change in X and Y of the final image
- X1 and Y1 are the change in X and Y of the original image
Scale Factor Dilation Definition
A scale factor dilation is a ratio of the length or area of an image before and after it has been enlarged or shrunk.
Scale Factor Dilation Example
How to calculate a scale factor dilation?
- First, determine the change in X and Y of the original image.
Measure the change in X and Y of a single length of the original image.
- Next, determine the change in X and Y of the modified image.
Measure the change in X and Y of the same length on the modified image.
- Finally, calculate the scale factor dilation.
Calculate the total scale factor dilation using the equation above.
