Enter the change in x and change in y of a length along a shape or image pre and post scaling to calculator the scale factor dilation.
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 or 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.
FAQ
What is scale factor dilation?
A scale factor dilation is the rate at which an image or shape is enlarged or shrunk to produce a scaled version of the image.
