Coordinate rules (Translation, Reflection, Rotation)

Front

What is a translation in coordinate geometry?

Back

A translation is a transformation that moves every point of a figure or a space by the same distance in a given direction.

How do you reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, the new point will be (x, -y).

What is the definition of a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.
