  10. MFM 2P Minds On Convert the following (Use your charts!): 135mm = m 12g = kg 20 yards = m 207 inches = feet 12 miles = km 0.25 pounds = kg

  11. MFM 2P Lesson Six: Proportions • Learning Goals: • I can define proportional • I know the properties of similar triangles • I can use the idea of proportions to determine missing sides of triangles

  12. MFM 2P Lesson Six: Proportions • What does “Proportional” mean?

  15. MFM 2P Lesson Six: Proportions • Proportion means: • Two quantities have the same relative size • Two things have the same ratio (or percentage) • All sides of a shape increase by the same amount

  16. MFM 2P Lesson Six: Proportions What is a ratio? A ratioshows the relationship between two numbers with the same unit. Example: What is the ratio of boys to girls in this class?

  17. MFM 2P Lesson Six: Proportions Can ratios be represented in a different way? Fraction, decimal, percent, ratio form Example: Rewrite the ratio of boys to girls in this class?

  18. MFM 2P Lesson Six: Proportions Which are proportional? 8 : 16 15% 4 : 5 50%

  19. MFM 2P Lesson Six: Proportions Which are proportional? 3 : 5 60% 6 : 10

  20. MFM 2P Lesson Six: Proportions What is a mullet?

  21. MFM 2P Lesson Six: Proportions How could you compare these mullets?

  22. MFM 2P Lesson Six: Proportions How could you compare these mullets?

  23. MFM 2P Lesson Six: Proportions Which Mullet is more mullet-y? 12 cm 0.000013 miles 33 cm 0.00051 miles

  24. MFM 2P Lesson Six: Proportions What would it mean if two mullets had the same mullet ratio? We can compare to OR to

  25. MFM 2P Lesson Six: Proportions Are these mullets the same? Compare their Mullet Ratios! 12 cm 33 cm 8 cm 22 cm

  26. MFM 2P Lesson Six: Proportions Complete Mullet Ratio Worksheet

  27. MFM 2P Lesson Six: Proportions What do you remember about similarity?

  28. MFM 2P Lesson Six: Proportions How do you think this applies to triangles? 15 m 7.5 m 18 m 9 m 4 m 8 m

  29. MFM 2P Lesson Six: Proportions These triangles as similar. What must the unknown side lengths for triangle “B” be? 6 m 4 m A B 3 m 1.5 m

  30. MFM 2P Lesson Six: Proportions Are these triangles similar? How do you know? 9 cm 11.25 cm 7.5cm 6 cm 2.1 cm 3.15 cm

  31. MFM 2P Lesson Six: Proportions • In conclusion, you can tell if triangles are similar if: • They have all the same angles • Their side lengths are proportional
