Warm up

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.


Glide reflections

Glide Reflections

Translation, then Reflection

(Combos)


Glide reflections1

Glide Reflections

  • Combining a translation with a reflection.

  • Pay attention to the order!!


1 finding the image of a glide reflection

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)


2 finding the image of a glide reflection

2. Finding the Image of a Glide Reflection

A’(–6, 2)

Perform the Glide Reflection on A(–3, 5).

A’’(2, –6)


3 finding the image of a glide reflection

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)
