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