Translations
A translation is when you do this to a figure.
What is move it right, left, up, or down?
A reflection is when you do this to a figure.
What is flip it or make a mirror image of it?
A rotation is when you do this to a figure.
What is spin it?
The mark(s) used when labeling image points.
What is prime notation?
These characteristics do NOT change when performing a rigid transformation (reflection, rotation or translation).
What are shape and size?
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
What is (7,16)?
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.
What is (3,2)?
Find the new coordinates of (5,4) after you rotate the point with 180º.
What is (-5, -4)?
What are the two directions you can go when rotating a point or a pre-image?
What are clockwise and counterclockwise?
The transformation that would result in the same image as a 90 degree rotation clockwise.
What is a 270 degree rotation counterclockwise?
Write the notation of point (x,y) after it moves 3 spots to the left and 7 spots up.
What is (x-3,y+7)?
Write the notation of point (x,y) after it is reflected over the y-axis.
What is (-x,y)?
Write the notation of point (x,y) after it rotates 90º clockwise.
What is (y,-x)?
What is the origin?
These properties change under a reflection.
What are orientation and location?
Describe the translation for this notation: (x,y) --> (x + 8, y + 4)
What is a translation of 8 units to the right and 4 units up?
A picture with one point (-3,4) was reflected over a vertical line that is 2 units to the right of the point . What should be the new coordinates of the point?
What is (1, 4)?
Figure QRST has vertices Q(2,-1), R (6,-1), S(6,-3) and T(2,-3). Which will be the coordinates of vertex R after the rectangle is rotated 90º counterclockwise about the origin?
What is (1,6)?
The word used to describe a transformation where you "slide" points or an image left, right, up or down.
What is a translation?
This doesn't change after a translation of a figure.
What is orientation or size or shape?
The image points of ∆LMN after a translation of 6 units to the right and 4 units down. L(0,3) M(6,4) N(3,9)
What is L'(6,-1), M'(12,0), N'(9,5)?
The rectangle DEFG was reflected over the x-axis. Then translated 8 units up. Then reflected over a horizontal line that goes through the point (0,4) The original vertices are D(5,5) E(5,8) F(8,8) G(8,5). What are the coordinates of the new vertices?
What is D'(5,5), E'(5,8), F'(8,8), G'(8,5)?
Graph ∆JKL after a rotation of 180º about the origin. J(5,6) K(7,9) L (1,2)
What is J(-5,-6), L(-7,-9), L(-1,-2)?
The phrase used to describe when more than one transformation is needed to move a point or figure onto an image.
What is sequence of transformations?
This property SOMETIMES changes under a rotation.
What is location?
