Translations
Label and state the prime image of A(1, 4) after a translation 4 units up and 5 units left?
A'(5, -1)
When we are rotating do we move clockwise or counter clockwise?
Counter-clockwise
True or False: Reflections preserve size
True
True or False: A dilation is not an isometry or rigid motion.
True - A dilation is not an isometry or rigid motion because it does not preserve the size of the shape.
What is the definition of a prime image or image (they are the same)?
Shape after transformation has been performed
Translate L(-3, -2) A(0, -1) D(3, -2) 1 unit right and 3 units up.
L'(-2, 1) A'(1, 2) D'(4, 1)
True or False: Rotating a figure 90 degrees clockwise is the same as rotating a figure 270 degrees counterclockwise.
True
What is the new coordinate point of H(-7, 9) if you reflect it over the x-axis?
H'(-7, -9)
What is the new image of G(8, 10) if it undergoes a dilation by a factor of 25?
G'(200, 250)
When you rotate an image do you generally rotate clockwise or counterclockwise?
Counterclockwise
What is the translation rule if the points are going from A(-3, -4), B(-1, -4) to A'(3, -4), B'(5, -4)?
(x + 6, y)
What is the new image of Z(-4, 0) if you rotate it 270 degrees?
Z'(0, 4)
What are the points of the new image D(-1, -4) E(2, -4) F (2, 5) after a reflection over the x axis?
D'(-1, 4) E'(2, 4) F'(2, -5)
What is the dilation factor if A(-2, 3) mapped to A'(-1, 1.5)?
Dilation of 0.5 or 1/2
What is the difference between an enlargement of a shape and a reduction?
Enlargement is a dilation by a number bigger than 1, Reduction is a dilation by a number between 0 and 1.
What is the coordinate point of the PRE-IMAGE A given that A' is (8, -7) and underwent (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
What is the line of reflection if L(1, 4) M(1, 0) N (3,0) mapped to L'(5, 4) M'(5, 0) N'(3, 0)?
reflection over the line x = 3
Dilation of 1/4 of A(-4, -8) B(8, 12) C(-8, 4)?
A(-1, -2) B'(2, 3) C'(-2, 1)
What is the one transformation we have talked about that is not an isometry or rigid motion ?
Dilation
What is the new image of A(2, 4) B(3, -6) C( -6, -6) given (x, y) --> (x + 4.5, y - 2.3)?

What is the image of A(4, 0) B(5, 1) and C(4, -4) if it was reflected over the line y =x?
A'(0, 4) B'(1, 5) C'(-4, 4)
What is the image of D(-8, -12) E(-8, 12) F(12, -8) if it underwent a dilation by -4?
D'(32, 48) E'(32, -48) F'(-48, 32)
What is an isometry, or rigid motion?
Transformation that changes position without changing size or shape of figure.
