Warm up 1. Rotate P(-4, -4) 180 2. Rotate Q(-1, -3) 90 CCW 3. How many lines of symmetry do the following shapes have?

Translations A slide up or down and/or left or right

Coordinate Notation Translating left or right Translating up or down • To translate left, we subtract from our x-value. • To translate right, we add to our x-value. • To translate up, we add to our y-value. • To translate down, we subtract from our y-value. Ex: (x+5, y) or (x-3, y) Ex: (x, y+7) or (x, y-2)

Translate the following points and write the rule for each. 1. Translate A(3, 5) to the left 5. 2. Translate B(-1, 2) up 4. 3. Translate C(0, 2) down 6. 4. Translate D(1, 1) to the right 3 AND up 4.

Translate the image by (x – 8, y + 2)

Find the pre-image using (x + 12, y – 17)

Translate the following figure using the given rule: In which quadrant does A’B’C’D’ fall?

Write the rule for the translation given in the picture below:

PLICKERS Which of the following best represents the following translation:

Dilations • NOT an isometry. • Dilations are a resizing of the image. They change the lengths of the segments but NOT the ANGLES.
