Dilations Intro: What Do You Notice?

Play around with this constrution for a few minutes. As you do, carefully observe what happens. Be sure to move points A, B, and O around. Be sure to slide the slider too!

1)

What do you notice? What do you wonder? Spare no detail!

2)

What happens when [math]k=0[/math]?

3)

What happens when [math]k=1[/math]?

4)

What happens when [math]k[/math] lies between 0 and 1?

5)

What happens when [math]k[/math] lies between -1 and 0?

6)

What happens when [math]k>1[/math]?

7)

What happens when [math]k<-1[/math]?

Play around with this constrution for a few minutes. As you do, carefully observe what happens. Be sure to move points A, B, and O around. Be sure to slide the slider too!

8)

Check the box [math]\frac{OA'}{OA}[/math] in the upper right corner. How does the ratio [math]\frac{OA'}{OA}[/math] compare to the scale factor [i][b]k[/b][/i]? (Be sure to move points and slider around!)

9)

Check the box [math]\frac{OB'}{OB}[/math] in the upper right corner. How does the ratio [math]\frac{OB'}{OB}[/math] compare to the scale factor [i][b]k[/b][/i]? (Be sure to move points and slider around!)

10)

Check the box [math]\frac{A'B'}{AB}[/math] in the upper right corner. How does the ratio [math]\frac{A'B'}{AB}[/math] compare to the scale factor [i][b]k[/b][/i]? (Be sure to move points and slider around!)
