Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is a pre-image?

Back

The original figure before a transformation is called the pre-image.

Front

What is an image in geometry?

Back

The new figure that results from a transformation is called the image.

Front

What does a translation do to a figure?

Back

A translation slides a figure from one position to another without changing its shape or size.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

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

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape the same.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped in a reflection.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is turned during a rotation.
