What is a dilation?

Changing the size of your pre-image to get a similar shape. (Stretch or shrink)
200
What directions can you slide a figure for a translation?
Up, Down, Left, Right, or Diagonally
200
If your pre-image figure is in quadrant III and you reflect it across the y axis, what quadrant would your image be in?
Quadrant IV
200

If your pre-image is located in quadrant II and you rotate it counter clockwise 90 degrees, what quadrant would your image be located in?

Quadrant III

200
What does congruent mean?
Same size and shape
200

If the scale factor is 1, what is the relationship between the preimage and the image?

They both are the same

300
If point A is at (2,2) and you translate it left 5 units, what would the point at A' be?
(-3,2)
300
If point A is located at (5,6) and it is reflected across the x-axis, what would point A' be?
(5,-6)
300
If your pre-image is located in quadrant III and it is rotated 180 degrees, what quadrant would your image be located in?
Quadrant I
300
What is the line of symmetry?
It is the line that a figure is being reflected over.
300

If the scale factor is >1, what is the relationship between the preimage and the image?

The image is bigger than the preimage

400
If point J is at (3,-4) and you translate it left 5 units & up 7 units, what would the point at J' be?
(-2,3)
400
If point K is located at (-2,-4) and it is reflected across the y-axis then reflected across the x-axis, what point would K' have?
(2,4)
400
If you have point G at (-3,2) and you rotate it 90 degrees clockwise, what would the point G' be?
(2,3)
400
What is the point of rotation?
It is the point the figure is being rotated around.
400

If the scale factor is between 0 and 1, what is the relationship between the preimage and image?

The image is smaller than the preimage

500
If point W is at (-5,0) and first you translate it right 7 units & up 3 units then you translate it left 2 units & down 3 units, what would the point at W' be?
(0,0) or the origin
500
If point X is located at (-5,-5) and it is translated 8 units to the right and 2 units up then it is reflected across the y-axis, what would the point for X' be?
(-3,-3)
500
If you have point Q at (1,-4) and it is translated left 3 units & up 5 units then it is reflected across the y-axis and finally rotated 180 degrees, what point would Q' be?
(-2,-1)
500
What is a transformation AND what are the 3 examples of transformations we have learned so far?
A transformation is changing the pre-image to an image by sliding, flipping, or turning a figure. - The 3 transformations we have learned so far are: Translation, Reflection, Rotation
500

Why will you not see a scale factor that is negative?

Because scale factors of 0 and below completely get rid of the figure.
