Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, meaning the figure's dimensions remain unchanged.

How do you describe a rotation?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

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

Back

The effect of a 90-degree clockwise rotation on a point (x, y) is to transform it to the point (y, -x).

How can you identify a shape and its image after a reflection?

Back

You can identify a shape and its image after a reflection by checking if the image is a mirror image of the original shape across a specific line.
