Translations
If the coordinate point (1,2) is translated up 5 units, what is the new coordinate points?
(1,7)
If (3,7) is being reflected over the x axis, what is the new coordinate?
(3,-7)
What is the new point after (4,5) is rotated 180 degrees around the origin?
(-4,-5)
What is the rule for reflecting over the x axis?
x stays the same, y changes sign
What transformation means to move?
Translate
If coordinate point A is (-3,4) and it is translated to the left 1 unit, what is the new coordinate point?
(-4,4)
If (-2,-5) is being reflected over the y axis, what is the new coordinate?
(2,-5)
What is the new point if (-1,4) is rotated 90 degrees clockwise around the origin?
(4,1)
What is the rule for reflecting over the y axis?
Y stays, x changes sign
What transformation means to turn?
Rotate
Coordinates
A (0,3) B (1,2) are moved 1 unit up and 1 unit right.
What are the new points?
A (1,4)
B (2,3)
(8,-9)
(-3,7)
What is the new point if (-12,-5) is rotated 90 degrees counterclockwise around the origin?
(5,-12)
What is the rule for rotating 180 degrees around the origin
DO NOT FLIP
x and y change sign
What transformation means to mirror?
Reflect
A (-1,-1) B (-1,-5) C (-5,-1)
are all being moved 2 units down.
What are the new points?
A (-1,-3)
B (-1,-7)
C (-5,-3)
If (4,0) is reflected over the x axis FIRST, then the y axis, what is the FINAL coordinate point?
(-4,0)
What are the new points if (0,2) and (-3,4) are rotated 90 degrees clockwise around the origin?
(2,0) (4,3)
What is the rule for rotating 90 degrees clockwise around the origin?
flip x and y
change the sign of the new y
What is a rigid transformation?
Where the size and the shape do not change
A (-1,-1) B (-1,-5) C (-5,-1)
are being translated 3 units up and 1 unit right.
What are the new coordinates?
A (0,2)
B (0,-2)
C (-4,2)
(9,8) (8,-3) (-2,5) and (-1,-1) are all reflected over the x axis, what are their new coordinates?
(9,-8) (8,3) (-2,-5) (-1,1)
What are the new points after a 90 degree counterclockwise rotation around the origin for points
(9,4) (10,-2) (-3,4)
(-4,9) (2,10) (-4,-3)
What is the rule for rotating 90 degrees counterclockwise around the origin?
flip x and y
change the sign of the new x
