100
Translation
Transformation that slides each point of a figure the same distance and direction along a line.
100
Right, Left, Up, or Down
What are the four directions that a translation can move a figure?
100
Line of reflection
What do we call the line that acts as a mirror so that corresponding points are the same distance from the line?
100
True
True or False, a 90 degree clockwise rotation is the same as a 270 degree counterclockwise rotation?
100
False
True or False, Dilations creates congruent figures?
200
Rotation
Transformation that turns a figure on a plane about a fixed point
200
Move to the right 3 units
x + 3 describes what kind of movement?
200
X stays the same, Y changes to its' opposite (negative)
When a point (x,y) is reflected over the x-axis, what happens to the x and y?
200
(-3, -6)
What will happen to the point (3,6) if it is rotated 180 degrees?
200
The figure will stretch
When the scale factor is a number greater than 1, what happens to the figure?
300
Dilation
Transformation that stretches or shrinks a figure based on the scale factor.
300
Move down 2 units
y - 2 describes what kind of movement?
300
X changes to its' opposite (negative), Y stays the same
When a point (x,y) is reflected over the y-axis, what happens to the x and y?
300
(-7, -9)
What will happen to the point (9, -7) if it is rotated 90 degrees clockwise?
300
The figure will shrink
When the scale factor is a fraction, what happens to the figure?
400
Reflection
Transformation that flips a figure across a line of reflection.
400
Slide
What word do we associate with the movement of a translation?
400
(-2, 7)
The point (2,7) is reflected over the y-axis, what are its' new coordinates?
400
Turns
What is the word we associate with rotations to describe the movement?
400
(9, 15)
What will be the new coordinates if the original point is (3,5) and the scale factor is 3?
500
The image has prime symbols
How can you tell the difference between the pre-image and the image?
500
Move to the left 4 units and move up 3 units
(x - 4, y + 3) describes what kind of movement?
500
(8, 3)
The point (8,-3) is reflected across the x-axis, what are its' new coordinates?
500
Quadrant 1: +, +
Quadrant 2: -, +
Quadrant 3: -, -
Quadrant 4: +, -
What are the four quadrant rules?
500
(2, 3)
What will be the new coordinates if the original point is (4, 6) and the scale factor is 1/2?
