Solution. In order to determine whether $\triangle ABC$ and $\triangle PQR$ are similar, we need to find a sequence of dilations and rigid motions which will map $\triangle ABC$ to $\triangle PQR$. - To find the scale factor students could: a. divide 22” by 11” to get a scale factor of 2. But a scale factor of 2 would mean the other dimension would be 8 1 2 x 2 or 16” which is too large. 1 b. Divide 13” by 8 2 ” to get a scale factor of 1.53. A scale factor of 1.53 would mean the other dimension would be 11x1.53 or 16.83”. c.

- The corresponding vertex in the red triangle is (3, 2). To go from 6 to 3 and 4 to 2, you divide each by 2 (the scale factor). Voilà! To check, we can do the same thing with another vertex: (2, 6) goes to (1, 3). Again, that means we divide by 2. Since the final object is smaller than the original image, our scale factor has to be 0.5, not 2.
