Scale Factor Baby Pic
![[b][color=#ff0000][size=150]When two similar figures (pre-image and image) have a scale factor of 1, they are congruent (same size, same shape). [/size][/color][/b]](https://www.geogebra.org/resource/svpjvekh/SFnrYEhVBY3CXOI3/material-svpjvekh.png)
![[b][size=150][color=#ff0000]When two similar (same shape, different size) figures have a scale factor greater than 1, resulting image is larger than the preimage. (Notice that the measurements of the image are divided by the measurements of the pre-image.) [/color][/size][/b]](https://www.geogebra.org/resource/eqvqmzt9/TOucHPVmwjghECYb/material-eqvqmzt9.png)
![[size=150][b][color=#ff0000]When two similar figures have a scale factor less than 1, but greater than 0, the resulting image will be smaller than the pre-image. [/color][/b][/size]](https://www.geogebra.org/resource/rgzqxr2u/OrQbymVJemYFA5Qx/material-rgzqxr2u.png)
When the scale factor is 1.0, what are the length x width measurements of the photo?
Is the image the same, smaller than, or larger than the pre-image?
What are the length x width measurements of the photo after applying a scale factor of 6?
Is the image the same, smaller than, or larger than the preimage?
You work at a print shop. The client wants the original (pre-image) photo to be poster sized (60 x 80). What scale factor will you use?
Now try a scale factor that is less than 1 but greater than 0. What are the l x w measurements of the photo after a scale factor of .5 is applied?
Will the resulting image be larger, smaller or the same as the original photo?
What is the scale factor when the length x width of the photo is 6 x 8?
