Presentation Transcript

  1. Warm up • Rotate P(-4, -4) 180 • Rotate Q(-1, -3) 90 CCW • If a function is odd and one point on it is R(-3, 4). Name another point. • If a function is odd and one point on it is S(9, -10). Name another point.

  2. Glide Reflections Translation, then Reflection (Combos)

  3. Glide Reflections • Combining a translation with a reflection. • Pay attention to the order!!

  4. 1. Finding the Image of a Glide Reflection Use the information below to sketch the image of QRS after a glide reflection. Q(2, –3), R(4, –4), and S(5, –1) Q’’(-2, 2), R’’(-4, 1), & S’’(-5, 4)

  5. 2. Finding the Image of a Glide Reflection A’(–6, 2) Perform the Glide Reflection on A(–3, 5). A’’(2, –6)

  6. 3. Finding the Image of a Glide Reflection Perform the Glide Reflection on F(-4, 2), G(1, 4), H(3, 0), I(-1, -2) F’(-4, -2), G’(1, -4) H’(3, 0), I’(-1, 2) F’’(-2, –3), G’’(3, –5) H’’(5, -1), I’’(1, 1)

  7. Class Work Combinations of Transformations Practice WS
