Vocabulary
A way to change the position, size, or orientation of a shape on a coordinate plane.
What is a Transformation?
The type of transformation that slides the shape.
What is a translation?
The location of E' if E(0,0) was translated 10 units right, and 10 units up.
What is E'(10,10)?
The coordinate that changes if T(4,2) is reflected over the x-axis.
What is the y-coordinate?
(2 ---> -2)
The location of E' if E(1,5) was rotated 90 degrees.
What is E'(-5, 1) ?
The direction a rotation turns on the coordinate plane.
What is Counterclockwise?
The type of transformation that flips a shape.
What is a reflection?
The Quadrant W' would be in if W(3, 4) was translated 5 units left, 3 units down.
What is II?
The Quadrant W' would be in if W(-3, 4) was reflected over the y-axis.
What is I?
The location of E' if E(9, -8) was rotated 180 degrees.
What is E'(-9, 8)?
The Quadrant represented by a positive x-coordinate, but a negative y-coordinate.
For example A(5, -3)
What is IV?
The type of transformation that turns the shape.
What is a rotation?
C(-16, 24)
(x, y) ---> (x + 7, y - 26)
C'(?, ?)
What is C'(-9, -2) ?
C(-16, 24)
(x, y) ---> (x, -y)
Which axis are we reflecting and find the value of C'
What is the x-axis?
AND
What is (-16, -24)?
If you rotate an object 270 degree clockwise, how many degrees is that counterclockwise?
What is 90 degrees?
The shape BEFORE the transformation takes place (original shape)
What is the Pre-Image?
The type of transformation that neither changes the shape nor the orientation of the shape.
What is a translation?
The translation rule for moving a point or figure 4 units left, 13 units up.
What is (x, y) ---> (x -4, y + 13) ?
The reflection rule for moving a point or figure across the y-axis.
What is (x, y) ---> (-x, y)?
The location of E' if E(-6, 4) was rotated 270 degrees.
What is E'(4, 6) ?
The word the apostrophe (') represents.
For example A'(3, -4)
What is Prime?
Which transformation(s) change the orientation of the shape?
What is a reflection and rotation?
The Quadrant J' would be in if J(-300, 200) was translated 215 units right, 350 units down.
What is III?
The Quadrant D' would be in if D(-15, -40) was reflected over the y-axis.
What is IV?
If a pre-image is in Quadrant III, and then rotates 360 degrees, where does the image end up?
What is QIII? (Or same place)
