Scaled Copies and Corresponding Parts

Draw

Show one pair of corresponding points and two pairs of corresponding sides in the original polygon and its copy. Consider using colored pencils to highlight corresponding parts or labeling some of the vertices.

Open Ended

What scale factor takes the original polygon to its smaller copy? Explain or show your reasoning.
