Reflections + Translations

Front

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

How does translating a figure affect its coordinates?

Back

The x-coordinate changes when moving left or right, and the y-coordinate changes when moving up or down.

Front

What is the effect of translating a point (x, y) 3 units to the right and 4 units down?

Back

The new coordinates will be (x + 3, y - 4).

Front

What is the algebraic representation for reflecting a figure over the x-axis?

Back

(x, y) --> (x, -y)
