1. Notes Translations

2. Definition

3. Properties of Translations
The image is congruent to the original figure.
The orientation of the figure and its image are the same.

4. Translations can also be described by vectors.
A vector is a quantity that has both direction and magnitude (size). 15 G 10 F 5 5 10 15

5. Copy ABC and draw its image after each translation.

6. D(-3,2), E(-4,-4), F(2,-1); Every point moves 7 units to the right.
K(4,2), L(-1,2), M(4, -1); (a, b) (a+1, b-5)

7. Choose the coordinate notation that matches each translation described.
A. (a, b)  (a - 4, b + 6) B. (a, b) (a + 6, b + 4)
(a, b)  (a - 6, b - 4) D. (a, b) (a + 4, b + 6)
Every point moves 6 units to the right and 4 units up.
Every point moves 4 units to the right and 6 units up.
Every point moves 4 units to the left and 6 units up.
Every point moves 6 units to the left and 4 units down.
