Questions for Students
1. Which figure is the pre-image? the image? How do you know?
2. Without checking any of the boxes, what do you notice about the relationship between the two figures?
3. Click the boxes to show the angle measures for both figures. Move each endpoint on the pre-image. What do you notice about the angle measures?
4. Click the boxes to show the side lengths (hide the angles if you want to). Move each endpoint on the pre-image. What do you notice about the side lengths?
5. Use the slider to adjust the scale factor, how does this affect the angles?
6. Use the slider to adjust the scale factor, how does this affect the side lengths?
7. Using the slider, when is the image larger than the pre-image? Smaller? Equal?
8. When you adjust the slider, how does side AD relate to side A’D’? AB to A’B’?
9. Does your observation hold true if you change the scale?
10. Summarize how adjusting a scale factor affects the image. Include information about angles and sides.
