Dilations
the letter that denotes scale factor
What is 'k'?
This is the rule for a 90 degree counterclockwise rotation
What is (-y, x)?
A translation does this to the figure on a coordinate plane
What is slide?
This is the rule for a reflection over the x axis
What is (x, y)--->(x, -y)?
Dilations produce these types of figures
What are similar?
Length of a side of the image/length of the corresponding side of the preimage
What is the formula for scale factor?
This is the rule for a 180 degree rotation
What is (-x, -y)?
This is the algebraic expression to represent translations
What is (x+h, y+k)?
This is the rule for a reflection over the y axis?
What is (x, y)--->(-x, y)?
The corresponding sides of similar images are this
What are proportional?
The sale factor is greater than this number if the dilation enlarges the figure
What is 1?
If the preimage is located in Quadrant 1, this is the quadrant an image will be in after a 90 degree counterclockwise rotation and then a reflection over the x axis
What is Quadrant 3?
These are the coordinates of A' after point A (-6, 4) is translated 3 units to the left and 4 units to up
What is (-9, 8)?
This is the general rule after a figure is reflected over the x axis and then over the y axis
What is (x,y)---> (-x, -y)
Finding the ratio of corresponding sides of a figure and its image after a dilation will give you this
What is scale factor?
This coordinate pair represents P' after P(5, -3) was dilated by a scale factor of 3, centered at the origin
What is (15, -9)?
A rotation is this type of transformation
What is a Rigid Transformation?
These are the coordinates of Z" after point Z(-3, -4) is rotated 90 degrees counterclockwise and the translated according to the rule (x+2, y)
What are (6, -3)?
This is the line over which an object is reflected
What is a reflection line or mirror line?
Similar figures have corresponding angle measures that are this
What are congruent?
This will happen to the figure if the scale factor is between 0 and 1 (0<k<1)
What is shrink?
This rotation will map the image onto the preimage (certain amount of degrees)
What is 360 degres?
Translations preserve this
What is congruence?
Point S is reflected over the x axis to form S'.Line segment SS' is this to the y axis
What is parallel?
Congruent figures are this
What is same shape and size?
