Rigid Transformations Practice

Front

What is a rigid transformation?

Back

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

Front

List the three types of rigid transformations.

Back

1. Translation 2. Rotation 3. Reflection

Front

What happens to the size and shape of a figure during a rigid transformation?

Back

The size and shape remain unchanged.

Front

What is the effect of a 90° clockwise rotation on the point (x, y)?

Back

The new coordinates will be (y, -x).

Front

What is the effect of a 270° clockwise rotation on the point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the effect of a reflection over the x-axis on the point (x, y)?

Back

The new coordinates will be (x, -y).

Front

What is the effect of a reflection over the y-axis on the point (x, y)?

Back

The new coordinates will be (-x, y).

Front

What is the effect of a translation on a point (x, y) by (a, b)?

Back

The new coordinates will be (x + a, y + b).

Front

What does it mean for transformations to preserve angle measurements?

Back

The angles between lines or segments in the figure remain the same after the transformation.

Front

What is the difference between rigid and non-rigid transformations?

Back

Rigid transformations maintain size and shape, while non-rigid transformations can change size and shape.
