Rigid Motion Transformations

Front

What is a Rigid Motion Transformation?

Back

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

Front

What is a translation in geometry?

Back

A type of rigid motion where a figure is slid from one position to another without rotation or reflection.

Front

How do you translate a figure 2 units to the right and 9 units down?

Back

Add 2 to the x-coordinate and subtract 9 from the y-coordinate of each point in the figure.

Front

What is the pre-image in a transformation?

Back

The original figure before any transformation is applied.

Front

What happens to the coordinates of a point when it is reflected across the x-axis?

Back

The y-coordinate changes sign, while the x-coordinate remains the same.

Front

What is the result of reflecting the point (4, -5) across the x-axis?

Back

(4, 5) - the y-coordinate changes from -5 to 5.

Front

What is a reflection in geometry?

Back

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

Front

What is the effect of a rotation on a figure?

Back

A rotation turns a figure around a fixed point, changing its orientation but not its shape or size.

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.

Front

What is the difference between an image and a pre-image?

Back

The image is the result of a transformation applied to the pre-image.
