Unit 5 – Transformations in the Plane Coordinate AlgebraEOCT Review
Key Ideas • Precise definitions: • Angle • Circle • Perpendicular lines • Parallel lines • Line Segment
Unit 5 - Transformations • Represent transformations in the plane • Compare rigid and non-rigid • Translations • Rotations • Reflections • Understand Dilations
Key Ideas • Given shapes – • Determine which sequence of rotations and reflections would map it on itself • Develop definitions of rotations, reflections and translations
Translations • Translate C(-4, 7) by (x – 7, y – 9). C’(-11, -2)
Reflections • Reflect across the y-axis
Examples Describe every transformation that maps the given figure to itself.
