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 translation in rigid transformations?

Back

A transformation that slides a figure from one position to another without turning it.

Front

What is reflection in rigid transformations?

Back

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

Front

What is rotation in rigid transformations?

Back

A transformation that turns a figure about a fixed point at a certain angle and direction.

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 do you translate a figure 2 units to the left and 5 units up?

Back

Subtract 2 from the x-coordinates and add 5 to the y-coordinates of each point.

Front

What does it mean to reflect a figure across the y-axis?

Back

To flip the figure over the y-axis, changing the sign of the x-coordinates of each point.

Front

What is the angle of rotation?

Back

The degree measure that indicates how far a figure is turned around a fixed point.

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.
