Basic 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 Rotation?

Back

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

Front

What is the Center of Rotation?

Back

The fixed point around which a figure is rotated.

Front

What is a Reflection?

Back

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

Front

What is a Line of Reflection?

Back

The line over which a figure is reflected.

Front

What is a Translation?

Back

A rigid transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What is the difference between Rotation and Reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

Can a Rigid Transformation change the size of a figure?

Back

No, rigid transformations do not change the size or shape of a figure.

What is an example of a real-life Rotation?

Back

The hands of a clock moving around the center.

Front

What is an example of a real-life Reflection?

Back

Seeing your image in a mirror.
