Identifying 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

Define translation in geometry.

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, called the center of rotation, by a certain angle.

Front

What does CCW stand for in transformations?

Back

Counterclockwise, indicating the direction of rotation.

Front

What is a reflection?

Back

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

Front

What is the line of symmetry?

Back

A line that divides a figure into two mirror-image halves.

Front

What is the resulting figure called after a transformation?

Back

Image.

Front

What is the pre-image in transformations?

Back

The original figure before any transformation is applied.

Front

How do you identify a 90-degree rotation?

Back

A rotation that turns a figure 90 degrees counterclockwise around a point.

Front

What is the difference between rotation and reflection?

Back

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