Translations
What is it called to slide an image left, right, up, or down?
Translation (slide, flip, or turn)
Describe what happens to an image during a reflection (slides, flips, turns)
Flips
An image in Quadrant 1 which turns 90 degrees clockwise moves to Quadrant 4, 3, or 2.
Quadrant 4
The image turned 90 degrees counterclockwise
Rotation?
6 - 10 =
-4
Describe what would happen to an image that moves using the rule (x,y) --> (x + 4, y)
Moves 4 units to the right
The 2 properties that are preserved when an image is flipped
Size and shape
Describe what happens to an image during a rotation (slides, flips, turns)
Turns?
The image slide 4 units to the right and 1 unit down
Translation
-5 + 1 =
-4
What 3 properties are preserved when an image is translated
Shape, size, and orientation
Identify the coordinate that stays the same when an image is flipped over the x-axis
The x-coordinate
An image turns 90 degrees clockwise, describe what happens to the x- and y- coordinates. The coordinates swap places or the coordinates stay is the same place
The coordinates swap places.
The image turned 180 degrees counterclockwise
Rotation
The opposite of -3
3
Point A (3, 4) slides 2 units to the right. Determine point A' (x, y) --> (x+2, y)
A' (5, 4)
Write the rule when an image flips across the x-axis. (x,y) -->
(x, -y)
The property that changes when an image is turned.
Direction (orientation)
The image flipped across the y-axis
Reflection?
-10 + 3
-7
Point B (5, 8) slides down 4 units. Determine point B' (x,y) --> (x, y-4).
B' (5, 4)
Using the rule (x,y) --> (x, -y), identify the axis the image flips across (x-axis or y-axis)
The x-axis
An image in Quadrant 3 turns 180 degrees. Identify which Quadrant the image moves to ( 1, 2, or 4)
Quadrant 1
(x,y) --> (x, -y)
Reflection across the x-axis
(- 4) * (- 5)
