Transformations

 Rigid transformations: Rotations, Reflections, and Translations

Dilations do not take part in this section

Rotate is to turn over the origin.

Rules when rotation a figure over the origin: Reflect: To flip over an axis or a line
 * Rotating 90 degrees clockwise/270 degrees counterclockwise: x,y turns into (-y,x)
 * Rotating 180 degrees: x,y turns into (-x,-y)
 * Rotating 270 degrees clockwise/270 degrees counterclockwise: x,y turns into (y,-x)

Function Notation of Reflections:
 * -f(x) = Over x-axis: Negate a, b, and c
 * f(-x) = Over y-axis: Only negate the x value Translate: To shift a figure horizontally and/or vertically Dilate: To vertically or horizontally stretch or compress
