Transformations: Who Am I?

Translation right

* I always preserve the orientation of a figure * I always preserve the size of a figure * I increase (+) just the x-value in an ordered pair

Translation up

* I always preserve the orientation of a figure * I always preserve the size of a figure * I increase (+) just the y-value in an ordered pair

Reflection over the x-axis

* I do not preserve the orientation of a figure * My image and pre-image are mirror images * If I start in Quadrant II, I'll end up in Quadrant III.

Dilation (decrease)

* I preserve shape but not size * My image and pre-image will be similar * I am created by using a scale factor that is LESS than one.

Rotation 180 degrees clockwise

* I will not change the size of a figure * I will change the orientation of a figure * I can be represented by (-x, -y)

Reflection over the y-axis

* I will not change the size of a figure * I will change the orientation of a figure * I can be represented by (-x, y)

Translation down

* I will not change the size of a figure * I will not change the orientation of a figure * I can be represented by (x, y - n) where n is any positive number

Translation left

* I will not change the size of a figure * I will not change the way a shape is facing * I can be represented by (x - n, y), where n is any positive number

Rotation 90 degrees clockwise

* My image and pre-image will be congruent * I do not preserve orientation * If I start at (3, 4), I'll end up at (4, -3)

Rotation 270 degrees clockwise

* My image and pre-image will be congruent * If I start in Quadrant I, I'll end up in Quadrant II * I can be represented by (-y, x)

Dilation (Increase)

*I preserve orientation * My pre-image and image will be similar. * I can be represented by (ax, ay), where a is any number GREATER than one.
