Presentation Transcript

  1. Translations Chapter 3 Section 6

  2. Transformations Transformation- is a change in a figures position, shape or size.

  3. Pre-images and Images The original image is the pre-image . * notated as point P or P The resulting figure after you flip, turn or slide is the image. * notated as P’

  4. Translation A translation- is a slide * Same distance in the same direction.

  5. Vectors To describe the translation we use a vector. < x units, y units> X- shows us how it moves left(-) or right(+) Y- shows us how it moves up(+) or down(-) Example: <-2, 3> <2, -3>

  6. Give the directions that the vector represents • <-3, 9> • <1, -7> • <0, 6>

  7. Example T<4, -2>(ABCD)

  8. Finding an Image T <1, -4> of ΔABC A B C

  9. Finding an Image T <2, 3> of ΔPQR

  10. Finding an Image T <-1, -2> of ΔABC

  11. Finding an Image T <3, 1> of ΔLMN

  12. Finding an Image T<3, 1> of ABCD A B D C

  13. Writing a Rule for the Translation First, decide how many spaces you move left or right. Then, decide how many spaces you move up or down. <right/left , up/down>

  14. Writing a Rule for the Translation A A’ B C B’ C’

  15. Writing a Rule for the Translation B A B’ A’ C D C’ D’

  16. Writing a Rule for the Translation A B A’ B’

  17. Write a rule to get someone from The History Museum to the Cable Car

  18. Translation Reflection Rotation Dilation
