• The same size and same shape.

• Equal to.

• The same transformation.

The original figure prior to a transformation.

• Pre-image

• Image

Describe the transformation:

(x, y) -> (x-2, y+7)

• Translation 2 units to the left & 7 units up

• Translation 2 units to the left & 7 units down

• Translation 2 units to the right & 7 units up

• Translation 2 units to the right & 7 units down

Write a rule for the translation.

•  (-x, y)

•  (x -2, y  + 1)
•  (x +2, y  - 1)
• ( 2x, 2y)

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis

• y-axis

• rotation 180

• translation 4 left

If the dotted figure is the image, what is the rule?

• ( x, y) -> ( x, -y)

• ( x, y) -> ( -x, y)

• ( x, y) -> ( y, -x)

Write the rule for this translation:
Slide 3 up and 2 right

• (x, y)---->(x + 3, y + 2)
• (x, y)-----> (x+2, y + 3)
• (x, y)----> ( 2x, 3y)
