Presentation Transcript

  1. Warm Up Tell whether the ratios form a proportion. Find the missing number.

  2. Translations I can: • Define and identify translations. • Understand prime notation to describe an image after a translation. • I can describe the changes occurring to the x and y coordinates of a figure after a translation. Vocabulary: • Transformations • Translations • Congruent Figures • Parallel lines

  3. Transformations change the position of a shape on a coordinate plane. *What that really means is that a shape is moving from one place to another.

  4. Translation (Slide) The action of sliding a figure in any direction. *We use an arrow to represent the direction of the slide.

  5. A translation does not need to be in a vertical or horizontal direction. • It can also be in a diagonal direction.

  6. Translation on Lines • The size stays the same, the object is just slid to a new location. • The lines are considered parallel lines- lines are parallel if they lie in the same plane, and are the same distance apart over their entire length.

  7. Translation on Angles • The angle degree stays the same, the angle is just slid to a new location.

  8. Congruent Figures Figures with the same size and shape.

  12. Prime Notation Way to label an image after a transformation. Example: A B A’ B’ (original before transformation)(image after transformation) A’ is read as “A prime.”
