2. Translation - Common name: Slide
(horizontally or vertically or both)
Rule: Add each point in the figure to a given point
Reflections - Common name: Flip
(over the x-axis or y-axis)
Rules:
*To reflect a point over the x-axis, keep the original x-coordinate and multiply the y-coordinate by -1. (negate the y) Example: A (4, -3) A’ (4, 3)
*To reflect a point over the y-axis, keep the original y-coordinate and multiply the x-coordinate by -1. (negate the x) Example: A (4, -3) A’ (-4, -3)

3. A figure can be enlarged or reduced through dilation.
Rotation - Common name: Turn
Rules for rotating about the origin:
(x, y) (-x, -y) ˚ clockwise or counter-clockwise
(x,y) (y, -x) ˚ clockwise
270˚ counter-clockwise
(x, y) (-y, x) ˚ counter-clockwise
270˚ clockwise
Dilation - Common name: Enlarge or Shrink
Dilate means “to make wide or larger.” Dilations change the size, but not the shape of a figure.
A figure can be enlarged or reduced through dilation.
Rule: When using the origin as the center of dilation, we multiply each point in an ordered pair by the scale factor.
***Scale factor greater than 1 = an enlarged figure
***Scale factor less than 1 = a smaller image
