Ans- You can decide if two figures are similar or not by looking at their: -General Shape -Corresponding angels -Corresponding side lengths -Ratio Ans. The Scale factor tells us in between two figures is that how much have those figures stretched or shrink. Ans 3- Example Q4. **Explain how you can use the scale factor to determine how the area of an enlarged figure compares to the area of the orignal shape.** Ans. The scale factor gets squared to find the area of an enlarged figure compare to the original shape's area.
 * Q1. How can you decide whether two figures are similar or not?**
 * Q2. What does a scale factor between two figures tell you?**
 * Q3. Explain how you can find a scale factor between two similar figures. Use an example to explain your thinking.**

__**Summary**__ This investigation was quite fun. In this investigation we learned how to find the scale factor, how you can know if the figures are similar or not.
