  10. measure

  11. Similar figures must have: (two things)

  12. Corresponding angles have the same measure, 2. corresponding sides have equivalent ratios.

  13. What is the relationship between 3 and 1/3 called?

  14. reciprocals

  15. What is the number 8 called in the rule (8x,8y)?

  16. coefficient

  17. If we apply the following rule, will we have similar figures? Why or why not? (.5x,.5y)

  18. Yes, the coefficients of x and y are the same

  19. What copier size factor would you apply to enlarge a figure 1.5 times?

  20. 150 %

  21. If the perimeter of one figure is 10, and the perimeter of a similar figure is 50, what was the scale factor used to enlarge the figure?
