This word describes translating.
Slide
The word that describes rotating
turning
The graph depicts a rigid transformation. What is the rule? Give the words and the notation.
1 unit right 2 units down: (x + 1, y - 2)
This rule describe translating up 6 units.
(x, y+6)
This notation (symbol) is how we indicate the figure from the image.
A' (apostrophe"
This word is another way to say reflecting.
flip
If both coordinates change signs what transformation occurred?
180 degree rotation
The given graph depicts a rigid transformation.
What is a reflection in the y-axis?
Describe this transformation rule: (x, + or - y)
reflect over the x-axis?
The picture below shows this type of transformation.
Rotation
If (1, 6) is translated to the left 3 and down 1, what are the new coordinates?
(-2, 5)
The segment below has been rotated 90o in what direction?
counter clockwise
The given graph depict multiple transformations of the pre-image *. This image depicts a Reflection of * across the y-axis.
What is D?
If (1,5) becomes (3,0) what is the transformation rule?
(x + 2, y - 5)
Name the rigid transformations.
Translations, rotations, reflections
The figure has been reflected over which line?
The x-axis
This is the coordinate M' after the figure below is rotated 180o clockwise.
(-6, -6)?
The given graph depicts a rigid transformation.
What is a 90-degree clockwise rotaition?
This rule describes rotating 270o clockwise.
(change the sign of y, x) or 90 degrees CCW
Which figure is the image in the following reflection:
the blue triangle
In words, what is the translation rule for the figure to image below?
left two units, up two units
This clockwise rotation is the same as rotating 90o counterclockwise.
270o clockwise
The given graph shows rigid transformations of the pre-image . Triangle * will have a Rotations of 90-degrees counterclockwise about the origin. Where will the new figure be?
What is figure B?
(+ or - y, x) is a description of rotating 270o counterclockwise or rotating 90o clockwise. True or False
Both!
This coordinate stays the same when a figure is reflected over the y-axis.
The y-coordinate
This is the algebraic rule of a translation that moves a figure 2 units left and 3 units up.
(x, y) → (x − 2, y + 3)
The counterclockwise measure of the angle of rotation of ABCD about the origin.
270 degrees
The given graph represents transformations of the pre-image *. This figure shows a Rotation of the pre-image clockwise about the origin.
What is figure C?
This is the rule for the following transformation
rotation 90 degree counterclockwise about the origin
(𝑥, 𝑦) → (−𝑦,𝑥)
Give the verbal description for (x,y) -> (x-4,y+0)
the figure moves 4 units to the right.
What would be the transformation in the illustration?
180 degree rotation
These two transformations have occurred to the given figure.
What is a Reflection across the x-axis and then translated 10 units right and 2 units up.
What is the rule for the given transformation.
Reflection across the y-axis (𝑥, 𝑦) → (−𝑥,𝑦)
