Rigid Transformations

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What is a reflection in geometry?

Back

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

Front

What is the pre-image in a transformation?

Back

The original figure before any transformation is applied.

Front

What is the image in a transformation?

Back

The resulting figure after a transformation has been applied to the pre-image.

Front

What does it mean to translate a figure?

Back

To slide a figure in a straight line from one position to another without changing its shape or size.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is the line of reflection?

Back

The line over which a figure is reflected to create a mirror image.

Front

What are congruent figures?

Back

Figures that have the same shape and size, but may be in different positions.

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure without changing its orientation, while a reflection flips it over a line.

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.
