A rotation is when you do this to a figure.
What is turn or spin it?
The original image before any transformation has taken place.
What is preimage?
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
What is (7,16)?
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.
What is (3,2)?
Find the new coordinates of (5,4) after you rotate the point counterclockwise 180º.
What is (-5,-4)?
Write the translation of point (x,y) after it moves 3 spots to the left and 7 spots up.
What is (x-3,y+7)?
Write the notation of point (x,y) after it is dilated with K=6.
What is (6x,6y)?
DOUBLE JEOPARDY (3X THE POINTS)!
Changing a figure using movements, mirrors, turns, and changing sizes.
What is a transformation?
Line segment CD was dilatedmby a scale factor of 2. The dilations of the image are C' (4,0) and D' (6,2). What are the coordinates of the original line segment?
What is C(2,0) and D(3,1)?
This property is preserved under a dilation.
What is shape?
Graph ∆JKL after a rotation of 180º about the origin. J(5,6) K(7,9) L (1,2)
What is J(-5,-6), L(-7,-9), L(-1,-2)?
Shapes that have the same shape or size.
What is congruent?
