Rigid Motion Transformations

Front

What is a rigid motion transformation?

Back

A transformation that preserves distances and angles, meaning the shape and size of the figure remain unchanged.

Front

What are the types of rigid motion transformations?

Back

Translation, rotation, and reflection.

Front

Define translation in the context of rigid motion.

Back

A transformation that slides a figure in a straight line from one position to another without changing its size, shape, or orientation.

Front

What is a rotation in rigid motion?

Back

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

Front

What is reflection in rigid motion?

Back

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

Front

What is the pre-image in transformations?

Back

The original figure before any transformation is applied.

Front

What is the image in transformations?

Back

The resulting figure after a transformation has been applied to the pre-image.

Front

How does a 90° counterclockwise rotation affect the coordinates of a point (x, y)?

Back

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

Front

What happens to the coordinates of a point (x, y) when reflected across the x-axis?

Back

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

Front

What happens to the coordinates of a point (x, y) when reflected across the y-axis?

Back

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