  1. Unit 5 – Transformations in the Plane Coordinate AlgebraEOCT Review

  2. Key Ideas • Precise definitions: • Angle • Circle • Perpendicular lines • Parallel lines • Line Segment

  3. Unit 5 - Transformations • Represent transformations in the plane • Compare rigid and non-rigid • Translations • Rotations • Reflections • Understand Dilations

  4. Key Ideas • Given shapes – • Determine which sequence of rotations and reflections would map it on itself • Develop definitions of rotations, reflections and translations

  5. Translations • Translate C(-4, 7) by (x – 7, y – 9). C’(-11, -2)

  6. Examples

  7. Reflections • Reflect across the y-axis

  8. Examples Describe every transformation that maps the given figure to itself.

  9. Rotations

  10. Practice Problems CW/HW
