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 translation in geometry?

Back

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

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

A rigid transformation that turns a figure around a fixed point at a certain angle.

Front

What does it mean for a transformation to be rigid?

Back

It means that the transformation does not alter the size or shape of the figure.

Front

Identify the transformation: A triangle is flipped over the x-axis.

Back

Reflection.

Front

Identify the transformation: A square is moved 3 units to the right and 2 units up.

Back

Translation.

Front

Identify the transformation: A rectangle is turned 90 degrees clockwise around its center.

Back

Rotation.

Front

Which transformation is NOT rigid?

Back

A transformation that changes the size or shape of a figure, such as dilation.

Front

What is the line of reflection?

Back

The line over which a figure is reflected to create a mirror image.
