|
Geometric Transformation |
Changing a set of all points (often a shape) by translating, reflecting, rotating or dilating it. |
|
|
Translation |
Shifting an image horizontally and/or vertically |
|
|
Horizontal Shift |
Moving Left or Right |
|
|
Vertical Shift |
Moving Up or Down |
|
|
Reflection |
Creating a mirror image over a line of a pre-image |
|
|
Pre-Image |
The original set of points to be transformed. |
|
|
Rotation |
Turning a figure around a fixed point. |
|
|
Dilation |
Resizing an image based on a scale factor. |
|
|
Scale Factor |
A number by which you dilate a figure. A number larger than one will result in a larger image and a number between zero and one will result in a smaller image. |
|
|
Function |
Relationship where every input maps to exactly one output. (In Math I your input was typically "x" with an output of "y") |
|
|
Geometric Transformation Function |
A relationship where a coordinate maps to a new coordinate. |
|
|
Notation for a Geometric Transformation Rule |
|
|
|
Notation for a function of "x" |
|
|
|
Notation for a Pre-Image Triangle Vertices A, B, and C |
|
|
|
Notation for the First Transformed image from a Pre-Image Triangle with Vertices A, B, and C |
|
|
|
Notation for the Second Transformed image from a Pre-Image Triangle with Vertices A, B, and C |
|
|
|
Domain |
Set of all inputs for a function |
|
|
Range |
Set of all outputs for a function |
|
|
Congruent |
Have the same shape and size |
|
|
Similar |
Have the same shape but different size |
