4. Translation If the shape is moved 6 spaces right and 4 spaces up

5. A The following shape is going to be translated 8 spaces right and 5 spaces down. Where will coordinate A’ be located? A’ (5, -1)

6. Dilation with a scale factor of 3

7. Find the scale factor that was used 2.4m 7.2m 2.4 ? = 7.2 3

8. Find the scale factor that was used 8m 16m 16 ? = 8 0.5

9. Find the scale factor that was used Triangle ABC is at coordinates: A(3, 0) B(1, 4) and C(5, 0) Triangle A’B’C’ is at coordinates: A’(4.5, 0) B’(1.5, 6) and C’(7.5,0) What scale factor was used to make the dilated triangle? 3 ? = 4.51 ? = 1.54 ? = 65 ? = 7.5 4.5 3 1.5 1 6 4 7.5 5 All of the answers have to be the same number So the answer is…… 1.5
