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 does a translation do to an image?

Back

Slides it.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation?

Back

A transformation that turns a figure around a fixed point at a certain angle.

Front

What is the line of reflection?

Back

A line across which a figure is flipped during a reflection.

Front

What happens to the coordinates of a point during a translation?

Back

The coordinates change based on the direction and distance of the slide.

Front

How do you identify a translation?

Back

By observing that the figure has moved without changing its orientation or size.

Front

What is the center of rotation?

Back

The fixed point around which a figure rotates.

Front

What is the difference between a rotation and a reflection?

Back

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

Front

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

Back

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