1. Transformations on a Coordinate Plane

2. TransformationsTransformations TypeDiagram A translation moves a figure left, right, up, or down A reflection moves a figure across its line of reflection to create its mirror image. A rotation moves a figure around a given point.

3. Translations Translations can move left or right on the x-axis, and up or down on the y-axis

4. Reflection A reflection moves a figure across its line of reflection to create its mirror image. Can be over the x or y axis, or even another line.A reflection moves a figure across its line of reflection to create its mirror image. Can be over the x or y axis, or even another line. Reflected over the yReflected over the y

5. Reflection Reflected over the xReflected over the x

6. Reflection This one is reflected over the -1 on the X.This one is reflected over the -1 on the X.

7. Rotations A rotation moves a figure around a given point.A rotation moves a figure around a given point. Usually over the origin, but can be over any point.

8. Use the given rule to transform the figure. Then describe the transformation. (4,5) (2,1) (4,1) Rule: (-x, -y) opposite of y’s Preimage Image (-4,-5) (-2,-1) (-4,-1) Rotates the figure 180° opposite of x’s

9. Use the given rule to transform the figure. Then describe the transformation. (4,5) (2,1) (4,1) Rule: (y, -x) Switch x, make negative Preimage Image (5,-4) (1,-2) (1,-4) Rotates the figure 90° Clockwise Switch y, leave positive

10. Use the given rule to transform the figure. Then describe the transformation. (4,5) (2,1) (4,1) Rule: (-y, x) Switch x, leave positive Preimage Image (-5,4) (-1,2) (-1,4) Rotates the figure 90° Counterclockwise Switch y, make negative

11. How did this move? Translation, right 6 down 2

12. How did this move? Reflection over X

13. How did this move? Reflection over -1

14. How did this move? Rotation, clockwise 90 degrees over x

15. How did this move? Rotation, counter clockwise 90 degrees over (1,1)
