What is turning a figure around a fixed point called the center of rotation.
This is the correct definition of a reflection...
What is a figure flips over a line of reflection in order to create a mirror image?
The figure before a transformation is called the _________, or the original figure. After a transformation, the new figure is called the __________.
What is pre-image, and image?
The four types of direction in a translation are...
What are up, down, left, and right?
In class, our center of rotation is the origin (the point _____), and we rotate in increments of ____ degrees.
What is (0,0), and 90 degrees?
True of false: When reflecting a figure, each reflected point of the figure should be the same distance from the line of reflection on the opposite side.
What is true?
Name the three types of transformations...
What is rotation, reflection, translation?
Translations are thought of as
What is slides?
Figures can be rotated _________ or ___________.
What is clockwise or counterclockwise?
What value stays the same when reflecting over the x-axis?
What is a the x-vale?

What is Z', "Z Prime?"
Write an algebraic representation for translating a triangle four units right and three units down.
What is (x,y) --> (x+4, y-3)?
Drawing dots on your white board, rotate a triangle 270 degrees.
What is a (teacher checked image)?
Reflect the point D(8, -6) over the y-axis. What are the coordinates of D'?
What is (-8, -6)?
Congruence refers to whether the pre-image and image have the same ____ and ______.
What is the size and shape?
Drawing dots on your white board, translate a square to the following: (x,y) --> (x-2, y+3). Label both squares!
What is (your teacher approved image)?
List the four types of rotations that can be done in rotations.
What is 90 (turns one quadrant), 180 (turns two quadrants), 270 (turns three quadrants), and 360 (full turn)?
Given the points A(1,2), B(2,3) and C(5,4) show a reflection over the x-axis without drawing the pre-image.
What is A'(-1,2), B'(-2,3), and C'(-5,4)?
Describe the difference between the orientation of the figure and the orientation of the vertices.
The orientation of the figure refers to whether the pre-image and image are facing the same direction on the coordinate plane.
The orientation of the vertices refers to the order in which the vertices are labeled, clockwise or counterclockwise.
