### Transformations

SOL 8.8

Horizontal Axis: x-axis

Vertical Axis: y-axis

Origin: intersection of the y-axis and the x-axis; point (0,0)

FLIP

It may say flip or reflect the figure over the horizontal axis or x-axis!

It may say flip or reflect the figure over the vertical axis or y-axis!

Keep the x, change sign on y

Keep the y, change sign on x

Turn

It may say rotate about the origin…

90 degrees

180 degrees

270 degrees

360 degrees

This was clockwise. How do you think it will change for counterclockwise?

switch the coordinates and change the sign of the 2nd new coordinate

switch the coordinates and change the sign of the 1st new coordinate

Change the sign on both coordinates

SLIDE

TranslateSlide

It may say translate the figure…

Right 3

Down 4

Left 2, Up 4

(4,-5) (right or left, up or down)

Add ordered pairs and place to be translated.

SHRINK

GROW

Dilate ½

(-4,6)

(-4,4)

(-2,4)

(-2,3)

(-2,2)

(-1,2)

Multiply

Next, there will be some examples. These examples are just asking you too identify the transformation on appearance only.
