Learning Targets
What is a scaled copy of a figure? Let’s look at some examples.
The second and third drawings are both scaled copies of the original Y.
However, here, the second and third drawings are not scaled copies of the original W.
The second drawing is spread out (wider and shorter). The third drawing is squished in (narrower, but the same height).
We will learn more about what it means for one figure to be a scaled copy of another in upcoming lessons.
Scaled Copy: A scaled copy of a figure is a figure in which every length in the original figure is increased or decreased by the same scale factor. For example, if you draw a copy of a figure in which every length is enlarged by 2, then you have a scaled copy with a scale factor of 2.
