A translation is when you do what to a figure?
Slide or Move the figure right, left, up, or down
A reflection is when you do what to a figure?
Flip it or make a mirror image of it.
A rotation is when you do what to a figure?
Turn or Spin
Figure A""B""C"" has experienced how many translations from figure ABC
4
What are three types of transformations?
Translation, rotation, reflection, or dilation.
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
(7,16)
Find the new coordinates of (3,-2) after you reflect the point over the y-axis.
(-3,-2)
After you rotate the point (5,4) 180º clockwise, what is the image?
(-5,-4)
A(-5,2)
1) 270 rotation CCW
2) reflected across x-axis
A' (2,5)
A''(2, -5)
Which transformation does not result in a congruent figure?
Dilation
Write the RULE of point (x,y) after it moves 3 spots to the left and 7 spots up.
(x-3,y+7)
What is the difference between congruent and similar?
Congruent is same shape and size
Similar is same shape only.
Name the rotation
180 Degrees
Describe the transformation:
B(-12, 8) to B' (-3, 2)
Shrink with a scale factor of 1/4
Point A(2,7) is translated 5 units left, 1 unit down
THEN reflected over the x axis
(-3,-6)
What is the pre-image of the point H'(9,3) after the translation (x+2,y-5)?
H(7,8)
Write the rule for the point (x,y) after it is reflected over the x-axis.
(x, -y)
What is the same as -90 rotation?
270
A(-4,1) B(-1,1) C(-1,5)
What are the new points of ABC when reflect across the y-axis?
A' (4,1)
B'(1, 1)
C' (1,5)
What property is changed under a dilation?
Size
