What do you do to a figure when you translate it?
Slide it
100
What does it mean to reflect an image?
Flip it
100
When you rotate a figure, what are you doing to the figure?
Turn it
100
What is a pre-image?
The original image
100

What do you need to know to perform a translation?

The rule (how many units to move left/right, and up/down)

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

What changes in a rotation:   shape, size, position, or orientation?

Only the position

200

What does congruent mean?

Same size and shape

200

What are the two "D's"  you need to know to perform a rotation?

1.  Direction (counterclockwise) and 

2.  the Degree (90, 180, 270)

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

How should you turn your paper to perform a 90 degree counterclockwise rotation?

1 turn to right

300

What changes in a translation:   shape, size, location, or orientation?

Only the Location, the shape stays congruent

300

What is the one thing you need to know to perform a reflection?

What line to reflect over (x axis or y axis)

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 270 degrees counterclockwise, what would the point G' be?

(2,3)

400

What is the line of reflection?

It is the line that a figure or point is being reflected over.

400

If you had point (x,y) and you were asked to rotate it clockwise 90 degrees, what would your new point be?

(y,-x)

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

If you want to rotate 270 degrees counterclockwise, how many times do you turn your paper (and in what direction?)

Turn your paper 3 times to the right.
