Transformations

Transformations

Move a figure around the coordinate grid. No change the size or shape of figure.
Change in X-Coordinate moves figure left and right* (horizontally, like x axis)
Subtract from x coordinate (Example Rule: X-2)	Add to the x coordinate (Example Rule: X+3)
Moves the figure to the left	Moves the figure to the right
Change in Y-Coordinate moves figure up and down* (vertically, like y axis)
Subtract from y coordinate (Example Rule: y-2)	Add to the y coordinate (Example Rule: y+3)
Moves the figure down	Moves the figure up

*It is common to make more than one transformation to a figure at one time.  For example, you could slide a figure up and over (x+4, y+2).

Change the Size of the Figure (to make a Similar Figure) -OR- Change the Size and Shape of the Figure
Change the Size of the Figure (to make a SIMILAR Figure) Multiply or Divide all the Coordinates or Line Segments by the SAME Scale Factor
Multiply both the x and y coordinates (or all line segments) by the same scale factor to make bigger similar figure Example rule: (3x, 3y)	Divide both the x and y coordinates (or all line segments) by the same scale factor to make smaller similar figure Example rule: (x2 , y2) can also be written as (½ x, ½ y)
Change the Size and Shape of the Figure (to make a NON- SIMILAR figure)
Multiply the x and y coordinates (or all line segments) by a different scale factor to make bigger non-similar figure) Example rule: (4x, 5y)	Divide the x and y coordinates (or all line segments) by a different scale factor to make smaller non-similar figure) Example rule: (x4 , y5) can also be written as (14 x, 15 y)
