Translations
What is a word that describes a translation?
A slide
A single word that describes what a rotation is
A turn.
A word that describes what a reflection is.
A flip.
List three types of transformations.
Translation, Rotation, and Reflection.
The coordinates of A' if A(0,0) translates 3 units the right.
(3,0)
90 degree clockwise is the same as how many degrees counterclockwise?
270
The rule for a reflection across the x-axis
(x,y) ---> (x, -y)
The point where the x-axis crosses the y-axis. At (0,0)
The origin.
Write the rule for a translation that moves 5 units to the right and 3 units up.
(x,y) ----> (x+5, x+3)
The rule for a 180 degree rotation.
(x,y) ---> (-x,-y)
The rule for a reflection across the y-axis.
(x,y) ----> (-x, y)
The name of the figure before any transformations have been done to it.
Pre-image.
Find the coordinates of M' and N' when MN with M(4, -1) and N(-3, 3) is translated one unit left and 2 units down.
M'( 3, -3)
N' ( -4, 1)
If point A(-2,3) in QII is rotated 90 degree counter clockwise, which quadrant does it land in?
QIII
What quadrant does Triangle ABC with A(3,1) B (6,4) and C(4,4) land in after reflecting it across the y-axis.
QII
The name of the figure after transformations have been done to it.
Image
Find the coordinates of X', Y', and Z' when triangle XYZ with X(0,3), Y(3, -2), and Z(4,0) is translated by the rule (x,y) ----> (x-5, y+ 1)
X'(-5, 4)
Y'(-2, -1)
Z'(-1, 1)
What are the coordinates for L' after rotating the point L(5,3) 90 degrees clockwise.
(-3, 5)
The coordinates of X' when XY with X(-3, 1) and Y(-1, 4) is reflected over the x-axis.
X'(-3, -1)
Which point belongs to the image?
A or A'
A'
