Translations "slides" |
* moves and object left or right and up or down on a coordinate plane ~ x-->left or right ~ y-->up or down summary: * shift right (add to x) * shift left (subtract from x) * shift up (add to y) * shift down (subtract from y) |
|
|
Reflection Across X - Axis |
* flips an object across the x - axis * the X value changes while the Y value changes signs ~ RULE : (X,Y)-->(X,-Y) ~ |
|
|
Reflection Across Y - Axis |
* flips an object across the y-axis * the Y value stays the same while the X value changes signs ~ RULE : ( X,Y) --> (-X,Y) ~ |
|
|
Reflection Across Y = X |
* object flips across the Y=X line * the X and Y values switch ~ RULE : (X,Y)-->(Y,X) ~ |
|
|
Reflection Across Y = - X |
* object flips across the line Y=-X * the X and Y value switch and their signs change ~ RULE : (X,Y)-->(-Y,-X) ~ |
|
|
Reflection Through The Origin |
* is an example of a point reflection * the signs of the X and Y values change for each ordered pair ~ RULE : (X,Y)-->(-X,-Y) ~ |
