Translations
If I'm translating a pre-image 5 units to the right and 3 units down. How would I write this as an Algebraic rule
(x,y)--->(x+5, y-3)
If Point A (6, -7) is reflected over the x-axis, what would my new coordinates for A' be?
A'(6, 7)
What is the rule for 180 degree clockwise and counterclockwise rotation?
(x,y)--->(-x, -y)
When a pre-image is dilated by a scale factor of 1, what would happen to the image?
It would stay the same.
What do we call a transformation that produces the same shape and size as the pre-image?
Congruent
If I'm moving right on the x axis, what is happening to my x-value.
Increasing
If point B (5,10) is reflected over the y-axis, what would the new coordinates be?
B' (-5, 10)
What is the rule for a rotation 90 degrees clockwise?
(x,y)--->(y, -x)
If a pre-image is dilated by a scale factor greater than 1, what happens to the image?
Enlarges
What do we call a transformation that produces an image with proportional sides and congruent angles?

The rule for a translation is (x,y)--->(x-7, y+5), explain how my x and y values are changing.
my x-value is decreasing by 7 and y-value is increasing by 5.
What is the rule that represents a reflection over the x-axis?
(x,y)--->(x,-y)
What is the rule for a rotation of 270 degrees counterclockwise?
(x,y)--->(y,-x)
If a pre-image is dilated by a scale factor less than 1, what would happen to the image?
reduce, shrink
A figure is transformed from quadrant IV to quadrant I. The pre-image and image are congruent figures, but the orientation of the figure changed. What is the transformation used?
A rotation 90 degrees counterclockwise
If I'm moving up on the y-axis, what is happening to my y-values?
Increasing
What rule represents a reflection over the y-axis?
( x, y)--->(-x, y)

A' (-6,-7)
If coordinate A(3,5) is dilated by a scale factor of 5, what would my A' be?
A' (15, 25)
Which transformation always has the same angle measure, side lengths, orientation of figure and vertices?
Translation
