Transformations
Translations
Reflections
Rotations
100
A type of transformation where the size of the object does not change.
What is a rigid transformation?
100
Moving an object about a plane by changing its x value and y value, in other words a sliding movement.
What is a translation?
100
A transformation that flips an object over a designated line.
What is a reflection?
100
Turning an object clockwise or counter-clockwise around a fixed point.
What is a rotation
200
A type of transformation where an object changes its size, but not its shape.
What is a non-rigid transformation or a dilation?
200
The image of A=(5,-8) after (x+9, y+7) has been applied.
What is A'=(14, -1)
200
The image of point A=(3,6) after a reflection over the x-axis.
What is A'=(3,-6)?
200
The image of the point K= (3,-5) after a rotation around the origin 270 degrees clockwise.
What is K'=(5, 3)?
300
The way that we name point A after applying a transformation to it.
What is A' or A prime?
300
The image of B=(1,3) after <-3,-7> has been applied.
What is B'= (-2, -4)?
300
What happens to a point when it has been reflected over the y-axis.
What is a horizontal change, or a negation of the x coordinate?
300
The rotation that results in the same image whether you go clockwise or counter clockwise.
What is a 180 degree rotation?
400
Translation; Rigid transformation Reflection; rigid transformation Rotation; rigid transformation Dilation; non-rigid transformation
What are the names and categories of the four types of transformations?
400
The image of line segment CD when C=(2, 8) and D=(4,3) after a translation of 4 to the left and 7 down.
What is segment C'D' where C' =(-2,1) and D=(0,-4)
400
The reflection of the point B=(-3,-9) over the y-axis.
What is B'=(3,-9)?

What is J' = (6,-4)
500
The object that is the result of transformation of a pre-image.
What is the image?
500
The notation used for a translation 1 unit to the right and 1 unit up that is not <1,1> or (x+1, y+1)
What is T(1,1)?
500
What happens to a point that has been reflected over the line y=x.
What causes the coordinates to switch and become negated?
