10.3 Transformations

Question	Answer
A flip is called a ...	Image: Reflection (binary/octet-stream)
A slide is called a ...	Image: Translation (binary/octet-stream)
a turn is called a ...	Image: Rotation (binary/octet-stream)
Translation (-8, -3): what do you do to every original (x, y) pair?	(x - 8, y - 3) Add -8 to every x, Add -3 to every y. Image: Translation ( 8, 3) (binary/octet-stream)
Reflection over the x-axis: what do you do to every original (x, y) pair?	Change each y to the opposite sign: (x, y) --> (x, -y) Image: Reflection Specific (binary/octet-stream)
Reflection over the y-axis: What do you do to every original x and y pair?	Change each x to the opposite sign: (x, y) --> (-x, y) Image: Reflection Y Axis (binary/octet-stream)
Rotation 90 degrees clockwise about the point (0,0): What do you do to every original (x, y) pair?	Switch places with x and y, then make the y the opposite sign: (x, y) --> (-y, x)
Rotation 90 degrees counterclockwise about the point (0,0): What do you do to every original (x, y) pair?	Switch places with x and y, then make the x the opposite sign): (x, y) --> (y, -x)
Rotation 180 degrees about the point (0, 0): What do you do to every (x, y) pair?	Switch places with x and y, then make both the y and the x the opposite sign: (x, y) --> (-y, -x)
