1. Compare the following ratios and describe the relationship. Why do you think it's true? Use words like [b]similar, scale factor, image, pre-image.[/b][br]a. [math]\frac{AB}{AB'},\frac{BC}{B'C'},\frac{AC}{AC'}[/math][br]b. [math]\frac{AC}{CC'},\frac{AB}{BB'}[/math]

2. Are the above relationships true for alldilations? Use the undo button to get rid of your dilation, then perform[br]dilations of 1/2, 3, and 5. Is there anything you need to add to your answer to[br]number 1 (particularly part b)? 

3. With your last dilation, draw LINES [icon]/images/ggb/toolbar/mode_join.png[/icon] CB andC'B'. Display their equations in y=mx+b form, and describe their relationship.[br]Using what you know about angles of similar figures, can you give a reason that[br]this is true?
