Identify Rigid Transformations

Front

What is a rigid transformation?

Back

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

Front

What is reflection in geometry?

Back

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

Front

What is translation in geometry?

Back

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

Front

What is rotation in geometry?

Back

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

Front

What is dilation in geometry?

Back

A transformation that changes the size of a figure but not its shape, by expanding or contracting it.

Front

What is a pre-image?

Back

The original figure before any transformation is applied.

Front

What is an image in geometry?

Back

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

Front

How many degrees is a full rotation?

Back

360 degrees.

Front

What does a 90-degree clockwise rotation look like?

Back

A rotation that turns a figure 90 degrees to the right around a center point.

Front

What does a 180-degree rotation about the origin do?

Back

It turns a figure upside down, placing it in the opposite quadrant.
