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 across the x or y axis?
A rotation allows you rotate an image clockwise these 3 different ways.
What is 90, 180, and 270 degrees?
A dilation is when you do this to a figure.
What is enlargement or reduction?
These are the three properties that may be preserved after transformations.
What are shape, congruency, and orientation?
The algebraic rule of a figure after it moves 3 units to the left and 7 units up.
What is (x-3,y+7)?
The algebraic rule of a figure after it is reflected over the y-axis.
What is (-x,y)?
The algebraic rule that represents a 90o rotation.
What is (y,-x)?
The algebraic rule of a figure with a scale factor of 6.
What is (6x,6y)?
This property is not preserved after a reflection.
What is orientation?
Find the new coordinates of (-10,-12) if you translate the point three units left and 4 units up.
What is (-13,-8)?
The new coordinates of (3,-2) if you dilate the point with a scale factor of 4.
What is (12,-8)?
This transformation is the only transformation that does not preserve congruency.
What is a dilation?
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 the line y-axis. What should be the new coordinates of the point?
What is (3,-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 clockwise about the origin?
What is (1,6)?
Line segment CD was dilated around the origin by a scale factor of 1/4. The endpoints of the image are C (4,0) and D (6,2). What are the coordinates of the endpoints of the line C'D'?
What is C'(1,0) and D'(1.5,0.5)?
These properties are preserved under a dilation.
What are shape and orientation?
Graph rectangle DEFG after a reflection over the x-axis. D(-5,5) E(5,-8) F(-8,8) G(-8,5)
What is D'(-5,-5), E'(5,8), F'(-8,-8), G'(-8,-5)?
Graph ∆JKL after a rotation of 270 degrees about the origin. J(-5,6) K(-7,9) L (-1,2)

This property is not preserved for most rotations.
What is orientation?
