Translations
Label and state the prime image of A(1, 4) after a translation 4 units up and 5 units left?
A'(-4, 8)
The formulas are normally for rotating figures this direction.
Counter-clockwise
True or False: Reflections preserve size and orientation.
False - orientation is not preserved under a reflection.
Solve x+7=-3
x=-10
What is the definition of a prime image?
Shape after transformation has been performed
Translate L(-3, -2) 1 unit right and 3 units up.
L'(-2, 1)
True or False: Rotating a figure 90 degrees clockwise is NOT the same as rotating a figure 270 degrees counter clockwise.
False
What is the new coordinate point of H(-7, 9) if you reflect it over the x-axis?
H'(-7, -9)
Solve 2x+3=5
x=1
When you rotate an image clockwise, are you rotating the direction of a clock or the opposite direction of a clock?
Direction of the clock
What is the translation if the points are going from A(-3, -4), B(-1, -5) to A'(3, -4), B'(5, -4)?
T(x + 6, y)
What is the new image of Z(-4, 0) if you rotate it 270 counter clockwise degrees?
Z'(0, 4)
What are the points of the new image D(-1, -4) after a reflection across y = -x
D'(4, 1)
Solve -3x + 4x = 0
x=0
After a transformation. How can you tell the difference between the image and pre-image?
Prime marks
What is the coordinate point of the pre-image A given that A' is (8, -7) and underwent T(x - 2, y + 3)
A(10, -10)
How many degrees was the figure rotated if the new image of X(-4, 2) Y(-4, 0) Z(0, 3) is X'(4, -2) Y'(4, 0) Z'(0, -3)?
Rotation of 180 degrees
Find the location of L' if L(3, 0) is reflected over the line x=3
L'(3, 0)
Solve 5m + 6 =-2(1 - 3m) +2
m = 6
While performing a translation, x-3 means what?
Left 3
What is the new image of A(2, 4) given (x, y) --> (x + 4.5, y - 2.3)?
A'(6.5, 1.7)
What is the pre-image of M'(-2, 2) after a rotating of 180 degrees?
M(2, -2)
What is the pre-image of A'(4, 0) across y =x?
A(0, 4)
Solve 4 - (v -3) = -9 - 5v
v = -4
The rotations are based on the center of rotation being what?
The origin
(0, 0)
