Front

What is the definition of a translation in geometry?

Back

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

Front

What is the definition of reflection in geometry?

Back

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

Front

What is the definition of dilation in geometry?

Back
