Scale Factor Baby Pic
[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]
[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]
[size=150][b][color=#0000ff]When the scale factor is 1.0, what are the length x width measurements of the photo? [/color][/b][/size]
[size=150][b][color=#0000ff]Is the image the same, smaller than, or larger than the pre-image? [/color][/b][/size]
[size=150][b][color=#0000ff]What are the length x width measurements of the photo after applying a scale factor of 6? [/color][/b][/size]
[size=150][b][color=#0000ff]Is the image the same, smaller than, or larger than the preimage? [/color][/b][/size]
[size=150][b][color=#0000ff]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]
[b][size=150][color=#0000ff]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]
[size=150][b][color=#0000ff]Will the resulting image be larger, smaller or the same as the original photo?[/color][/b][/size]
[size=150][b][color=#0000ff]What is the scale factor when the length x width of the photo is 6 x 8?[/color][/b][/size]
