Rotations, reflections, translations, and dilations are all types of...?
transformations
The word that describes translating.
Slide
The word that describes rotating
turn
This word is another way of saying reflecting
Flip
This rule describe translating up 6 units.
(x, y+6)
The graph depicts a rigid transformation. What is the rule?
1 unit right 2 units down: (x + 1, y - 2)
Which type of transformation doesn't change orientation?
translation
If (1, 6) is translated to the left 3 and down 1, what are the new coordinates?
(-2, 5)
If both coordinates change signs what transformation occurred? (-x,-y)
180 degree rotation
This coordinate stays the same when a figure is reflected over the y-axis.
the y-coordinate.
Describe this transformation rule: (x, y) maps to (x,-y)
reflection over the x-axis
The given graph depicts a rigid transformation.
What is a reflection in the y-axis?
The name given to the transformed figure or point.
the image
This is what happens to the coordinates if a figure translates up and to the left.
subtract from the x-coordinate and add to the y-coordinate?
This is the coordinate M' after the figure below is rotated 180o clockwise.
(-6, -6)?
This coordinate changes when a figure is reflected over the x-axis.
the y-coordinate
(x,y) maps to (-y,-x)
reflection over the line y=-x
The given graph depict multiple transformations of the pre-image *. This image depicts a Reflection of * across the y-axis.
What is D?
This notation (symbol) is how we indicate the figure from the image. *If A is the pre-image, what would the image be?*
A prime
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 figure has been reflected over this line.
the x-axis
This rule describes rotating 270o clockwise.
(x,y) maps to (y,-x)
The given graph depicts a rigid transformation.
What is a 90-degree clockwise rotaition?
A type of congruence transformation that preserves side length and angle measure.
Rigid Transformation
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)
What is the rotation from pre image to image?
90 degrees clockwise or 270 degree counter clockwise.
Reflect the triangle ABC over Y-axis with side lengths AB =3 units, BC = 4 units and AC = 5 Units. After reflection What is the length of BC?
4 Units.
(x,y) maps to (-x,-y)
Rotation of 180 degrees about (0,0)
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?
A dilation or composition of rigid motions with dilation.
similarity transformation
Give the verbal description for (x,y) -> (x-4,y+0)
the figure moves 4 units to the left.
What would be the transformation in the illustration?
180 degree rotation
Reflect triangle PQR over X axis, what is the angle measure for P' Q' R'? Angle Measure forP = 60, R=90, Q = 30
R' 90, P' 60, Q' 30
This is the rule for the following transformation
rotation 90 degree counterclockwise about the origin
(𝑥, 𝑦) → (−𝑦,𝑥)
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.
