Geometry Ch 9

Stepp's Prentice Hall Geometry Chapter 9 Transformations (sec. 1-5 only)

A(n) ____ is a change in position, shape, or size of a figure transformation
A ____ is a transformation in which all points in a figure move the same distance & direction translation
A(n) ___ is a transformation in which the preimage and its image are congruent isometry
Another word for reflection is ___ flip
To describe a rotation, you need to know the ___ and the ___ center, angle of rotation
Figures can have reflectional or rotational ___ symmetry
Which type of transformation results in a similar figure? dilation
A scale factor must be ____ greater than zero
Scale factors between 0 and 1 result in a ___ reduction
Enlargements occur when the scale factor is ___ bigger than one
To rotate dilate a figure, begin by drawing the line connecting a point to the ____ center
(x,y)  (x +3, y – 6) is an example of a rule for a ___ translation
A ___ is always counterclockwise unless otherwise stated rotation
If half of a figure could be folded to fit exactly over the other half, it has ___ symmetry
If the center for a transformation is not named, it is assume to be ___ (0,0)
Which transformations do not have a center?___ translations, reflections
an image and its preimage are ___ from the center of a rotation equidistant
How do you indicate the translation: move point 4 spaces to the left and three spaces up (x-4,y +3)
y=x is a line that passes thur the ___ and has a slope of ___ origin, one
y=4 is a ___line that passes thru (0,4) flat
x = 2 is a vertical line that passes thru__ (2,0)
An image of a point, and its preimage are equidistant from the line of ____ reflection
The line of reflection is the ___ ___ of the line connecting any point and its preimage perpendicular bisector
In a translation, a figure will fit exactly on top of its ___ image
In a rotation, the image and preimage are ___ congruent
In a dilation the image and preimage are congruent (true or false) false - they are similar
In a dilation, the image is always on the line connecting the center and the ____ preimage
If the scale factor is 3, and the distance to the image is 12, how far is it from the center to the preimage? __ 4
If the scale factor is 2 and the distance from the center to the preimage is 6, how far is it from the center to the image? 12
the distance from the image to the center divided by the distance from the peimage to the center = ___ scale factor
We skipped the lessons on ___ and ___ composite transformations and tesselatons
If you have two consecutive rules to follow in order to make a translation, you could simplify by ___ combining them into one rule by adding
