Translations
What do you do to a figure when you translate it?
Slide it
What does it mean to reflect an image?
Flip it
When you rotate a figure, what are you doing to it?
Turning it
If you are DILATING a figure, what are you doing to it?
Enlarging or reducing it
What directions can you slide a figure for a translation? (*There are 5!)
Up
Down
Left
Right
Diagonally
If the pre-image is in Quadrant III and you reflect it across the y axis, what quadrant would your image be in?
Quadrant IV (4)
If the pre-image is located in Quadrant II and you rotate it counter-clockwise 90 degrees, what quadrant would the new image be located in?
Quadrant III
If your scale factor is 1/3, are you reducing or enlarging it?
Reducing
What does congruent mean?
Same size, same shape
If point A is at (5, 3) and you translate it left 5 units, what would the new coordinates be?
A' - (0, 3)
If point A is located at (5, 6) and it is reflected across the x-axis, what would the new coordinates be?
A' - (5, -6)
If the pre-image is located in Quadrant III and it is rotated clockwise 180 degrees, what quadrant would the new image be located in?
Quadrant I
If point A is at (2, 3) and you dilate it by a scale factor of 3, what would your new point be?
Would this be a reduction or an enlargement?
A' - (6, 9)
Enlargement
What does similar mean?
Same shape, different size
If point J is at (3, -4) and you translate it 6 units left & 7 units up, what would the new coordinates be?
J' - (-3, 3)
If point K is located at (-3, -4) and it is reflected across the y-axis, what would the new coordinates be?
K' - (3, -4)
If the pre-image is located in Quadrant I and it is rotated counter-clockwise 270 degrees, what quadrant would the new image be located in?
Quadrant IV (4)
If you have a point at (4, 8) and you dilate it by a scale factor of 1/4, what is the new coordinate?
Would that be an enlargement or a reduction?
(1, 2)
Reduction
What is happening to a figure that goes COUNTER-CLOCKWISE?
It is ROTATING to the LEFT
If point W is at (-5, 0) and you translate it 5 units to the right & 3 units down, what would the new coordinates be?
W' - (0, -3)
If point C is located at (-3, 2) and it is reflected across the line x = 2, what would the new coordinates be?
C' - (7, 2)
If you have point Q at (2, -4) and it is rotated 90 degrees clockwise, what would the new coordinates be?
(-4, -2)
If point K is at (2, 4) and you dilate it by a scale factor of 3/2, what are the new coordinates?
Would that be an enlargement or a reduction?
K' (3, 6)
Enlargement
What is a transformation? (*There are 4!)
A transformation is changing the pre-image (original image) to a new image by sliding, flipping, turning, reducing, or enlarging it.
A tranSLation, reFLection, roTaTion, or dilation
