Front

What is a transformation in geometry?

Back

A change in position, size, or shape of a figure.

Front

What is a translation?

Back

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

Front

What is a rotation?

Back

A transformation that turns a figure around a fixed point at a certain angle.

Front

What is a dilation?

Back

A transformation that changes the size of a figure but not its shape.

Front

What is the difference between pre-image and image?

Back

Pre-image is the original figure, while image is the figure after transformation.
