The new figure after a transformation

Front

Translation

Back

Sliding a figure but not turning. To translate a figure left or right, add to the x-coordinate to move it right, or subtract from the x-coordinate to move it left. To translate a figure up or down, add to the y-coordinate to move it up, or subtract from the y-coordinate to move it down.

Translation Notation

Back

(x, y) –> (x + a, y + b)

Front

Vertex/Vertices

Back

The name of a Coordinate (Vertex A is located at (3,-4))

Front

Reflection

Back

A flip over a line, usually the x-axis or y-axis.

Front

Line of reflection

Back

The line that a figure is being reflected over.

Front

Reflect over the X-Axis

Back

To reflect a figure in the x-axis, take the opposite of the y-coordinate. (x, y) → (x, −y)

Front

Reflect over the Y-Axis

Back

To reflect a figure in the y-axis, take the opposite of the x-coordinate. Reflection in y-axis: (x, y) → (−x, y)
