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 and angles remain unchanged.

What is a rotation in geometry?

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 translation in geometry?

Back

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

How do you identify a reflection over the y-axis?

Back

To identify a reflection over the y-axis, the x-coordinates of the points in the figure change sign, while the y-coordinates remain the same.
