Unit 3: Topic 2 Project - Non-Rigid Transformations Scale Factor
[b][size=150][color=#1e84cc]When two similar figures (pre-image and image) have a scale factor of 1, they are congruent (same size, same shape). [/color][/size][/b]
[b][size=150][color=#1e84cc]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]
[size=150][b][color=#1e84cc]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]
[size=150][b][color=#1e84cc]When the scale factor is 1.0, what are the length x width measurements of the photo? [/color][/b][/size]
When the scale factor is 1.0, the length x width of the photo is 3 x 4
[size=150][b][color=#1e84cc]Is the image the same, smaller than, or larger than the pre-image? [/color][/b][/size]
[size=150][b][color=#1e84cc]What are the length x width measurements of the photo after applying a scale factor of 6? [/color][/b][/size]
The photo's length x width measurements after applying a scale factor of 6 would be 18 x 24
[size=150][b][b][color=#1e84cc]Is the image the same, smaller than, or larger than the preimage? [/color][/b][/b][/size]
[size=150][b][color=#1e84cc]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? [/color][/b][/size]
You will need to use a scale factor of 20 to create an image from the pre-image photo that measures 60 x 80.
[b][size=150][color=#1e84cc]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? [/color][/size][/b]
The l x w of the photo after a scale factor of .5 has been applied is 1.5 x 2
[size=150][b][color=#1e84cc]Will the resulting image be larger, smaller or the same as the original photo?[/color][/b][/size]
[size=150][b][color=#1e84cc]What is the scale factor when the length x width of the photo is 6 x 8?[/color][/b][/size]
