1. Unit 3 Lesson 3 – Dilations on the Coordinate Plane

2. Page 12 C”

3. Page 12 They are well scaled dilations - scale factor 2. They are the same shape and size. A Translation

4. Page 13 ReflectionRotation Translation

5. Page 13 Yes, they change the size of a figure. No, they change the size of a figure and rigid motions only change the position of the figure.

6. Page 14 All angle measure is preserved but the sides are three times larger. All angle measure is preserved but the sides are smaller by half. The figure is unchanged. Multiplication

7. Page 14 (4, -8) (3, 5) (2x2, -4X2)= Scale factor of 4

8. Page 15... N(2, 8) A(-6, 0) P(4, -2) A’(-3, 0) P’(2, -1) N’(1, 4)...

9. Page 16... A(1, 3) B(-2, 2) C(0, -2) B’(1, 0) C’(3, -4) A’(4, 1) A”(8, 2) B”(2, 0) C”(6, -8)......
