Transformations
When the pre-image and image are the same size and shape, is it congruent or similar?
Congruent
Another name for translation
What is Slide?
Another name for Rotation.
What is Turn?
Another name for Reflection.
What is Flip?
Another name for Dilation.
What is Enlargement or Reduction?
When the pre-image and image are the same size and shape the two are said to be
What is congruent?
This notation (x,y) ---> (x-1, y-1) means what
What is left one and down one?
This is the rule for a 90 degree counterclockwise rotation about the origin.
What is (x,y) ---> (-y, x)
This is the rule for a reflection over the x-axis.
What is (x, y) ---> (x, -y)
This is the number that causes the dilation.
What is Scale Factor?
This transformation is not a congruence transformation.
What is Dilation?
If the image of point A is A', then this is the pre-image of point B'?
What is point B?
This is the rule for a 180 degree rotation about the origin.
What is (x,y) ---> (-x, -y)
This is the rule for a reflection over the y-axis.
What is (x, y) ---> (-x, y)
This is the operation one performs with the scale factor.
What is Multiply or Multiplication?
Which transformation changes the orientation of the figure and vertices?
Reflection
This is the translation rule for M(5, -1) ---> M'(-2, -4)
What is Left 7 and Down 3?
This is the rule for a 270 degree counterclockwise rotation about the origin.
What is (x,y) ---> (y, -x)
This is the rule for a reflection over the line y = x.
What is (x, y) ---> (y, x)
This is the image of point S with coordinates ( -3, 8) after dilation with scale factor 2.
What is (-6, 16)?
The transformations that are congruence transformations.
What are Reflection, Rotation, and Translation?
A translation is a type of this Transformation.
What is congruence or isometry?
This is the rule for a 90 degree clockwise rotation about the origin.
What is (x,y) ---> (y, -x)
This is the rule for a reflection over the line y = -x.
What is (x, y) ---> (-y, -x)
This is the pre-image of point W' with coordinates (-10, -2) after dilation with scale factor 1/2.
