1. **State the problem:**
We need to find a series of transformations that map polygon ABCDE with vertices near (1,3), (1,2), (2,1), (3,1), (3,3) onto polygon A'B'C'D'E' with vertices near (-6,-5), (-7,-3), (-9,-5), (-9,-7), (-7,-8).
2. **Identify the transformations:**
We observe that ABCDE is in the first quadrant and A'B'C'D'E' is in the third quadrant, larger and reflected.
3. **Step 1: Translation to origin (optional for clarity):**
Translate ABCDE so that vertex A at (1,3) moves to the origin by subtracting (1,3) from all points.
4. **Step 2: Reflection about the origin:**
Reflect the polygon about the origin, which maps $(x,y)$ to $(-x,-y)$.
5. **Step 3: Dilation (scaling):**
Calculate scale factor by comparing distances. For example, distance from A to B in ABCDE is approximately $\sqrt{(1-1)^2+(3-2)^2}=1$.
Distance from A' to B' in A'B'C'D'E' is approximately $\sqrt{(-6+7)^2+(-5+3)^2}=\sqrt{1^2+2^2}=\sqrt{5}$.
Scale factor $k=\sqrt{5}$.
6. **Step 4: Translation to final position:**
Translate the reflected and scaled polygon so that the origin maps to A' at $(-6,-5)$.
7. **Summary of transformations:**
- Translate by $(-1,-3)$ to move A to origin.
- Reflect about origin: $(x,y) \to (-x,-y)$.
- Dilate by factor $k=\sqrt{5}$.
- Translate by $(-6,-5)$ to move origin to A'.
This series maps ABCDE onto A'B'C'D'E'.
