Rigid Transformations vs. Non-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 is a non-rigid transformation?

Back

A transformation that alters the shape or size of a figure, such as dilations.

Front

What is a dilation?

Back

A transformation that produces an image that is the same shape as the original, but is a different size; it can be an enlargement or a reduction.

Front

What is a translation?

Back

A rigid transformation that moves every point of a figure the same distance in the same direction.

Front

What is a rotation?

Back

A rigid transformation that turns a figure around a fixed point called the center of rotation.

Front

What is a reflection?

Back

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

Front

What is the difference between enlargement and reduction in dilations?

Back

Enlargement increases the size of a figure, while reduction decreases the size of a figure.

Front

How do you identify a rotation transformation?

Back

By observing that the figure has been turned around a point, maintaining its shape and size.

Front

How do you identify a reflection transformation?

Back

By observing that the figure has been flipped over a line, creating a mirror image.

Front

What is the center of dilation?

Back

The fixed point in a dilation from which all points are expanded or contracted.
