Translations
What's the general way to think about a translation?
Slide or Shift
What's the general way to think about a Reflection?
What's the general way to think about a Rotation?
Turn or Twist
What's the general way to think about a Dilation?
Grow or Shrink
What are the two other words that sometimes get used to describe a compound transformation?
Compose or Composite
Which of the "four" characteristics of a transformation (Size, Shape, Orientation, Position) does change in a translation?
Position
Which two the "four" characteristics of a transformation (Size, Shape, Orientation, Position) does change in a Reflection?
Orientation & Position
Which two of the "four" characteristics of a transformation (Size, Shape, Orientation, Position) does change in a Rotation?
Position & Orientation
Which two of the "four" characteristics of a transformation (Size, Shape, Orientation, Position) does NOT change in a Dilation?
Shape & Orientation
What kind of shape is the result of any of the "rigid" transformations?
Congruent
What are the four directional rules when it comes to translating a point on the coordinate plane?
x+ right, x- left
y+ up, y- down
Which "directions' does a reflection over either axis result in an image being flipped, when starting in quadrant 1?
x-axis - flips down to Q4
y-axis, flips left to Q2
Which counterclockwise rotation will NOT change anything about the shape?
rotation of 360
A dilation is will scale up if k>1 and down if 0<k<1. What happens if k=1 or k=0?
k=0, the shape disappears
What kind of shape is the result any time a Dilation occurs?
The point K(-3,7) is translated using the rule (x+4, y-9). Where is the point K' located?
K' is at (1,-2)
The point K(5,1) is reflected over the y-axis; what's the location of K' ?
K' is at (-5,1)
The point K (2,7) is rotated CC270. Where is the new point K' located?
K' is at (7,-2)
The point K (3,6) is dilated by a scale factor of k=1/3.
What's the transformed point K' ?
K' is (1,2)
The point K (3,5) has two transformation applied.
1) Translate (x+2, y-3)
2) Reflect over the x-axis
What's the location of the point K" ?
K" (5,-2)
Triangle ABC has been shifter via translation. If the corner A(-3,5) has become A'(3,6); what translation rule resulted in the shift?
(x+6, y+1)
Triangle EFG is reflected over an axis. If point E(6,7) becomes point E' (6,-7) as a result of this reflection, which axis was reflected over?
x-axis
Triangle EFG is rotated around the origin. If point G (-5,1) becomes point G' (5,-1); which rotational angle was used?
180 degree rotation
The triangle ABC has points A(-2,3), B(-4,6) & C(-3,0).
What is point B' after a dilation where k=3?
B' is (-12,18)
Reflecting over the x-axis, followed by the y-axis, is the same as this single type of transformation.
Rotation of 180
