  1. 9.2 : Translations I can draw translations in the coordinate plane. Agenda: Check Homework 9.2 Notes

  2. If the images to the right describe a translation, in your own words, define translation:

  3. Vocabulary! A transformation that moves a figure the same distance in the same direction. It maps each point to its image along a vector. The vector in which a translation maps each point to its image. Each segment joining a point and its image has the same length as the vector and is parallel to the vector. A vector expressed as an ordered pair, where a represents the horizontal change and b is the vertical change from the vector’s tip to its tail.

  4. Vocabulary!

  5. Example 1: a) Graph TUV with vertices T(–1, –4), U(6, 2), and V(5, –5) along the vector .

  6. Example 1: b) Graph pentagon PENTA with vertices P(1, 0), E(2, 2), N(4, 1), T(4, –1), and A(2, –2) along the vector .

  7. Example 2: The graph shows repeated translations that result in the animation of the raindrop. a) Describe the translation of the raindrop from position 2 to position 3 in function notation and in words.

  8. Example 2: The graph shows repeated translations that result in the animation of the raindrop. b) Describe the translation of the raindrop from position 3 to position 4 using a translation vector.

  9. Example 3: Given the rule, , describe in component form. Then transform the figure given the vector.
