### 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

Translation, then Reflection

(Combos)

### Glide Reflections

• Combining a translation with a reflection.

• Pay attention to the order!!

### 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

A’(–6, 2)

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

A’’(2, –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)
