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 rigid transformations?

Back

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

Front

What does it mean to reflect a figure?

Back

To flip a figure over a line (line of reflection) to create a mirror image.

Front

What is a 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 line of symmetry?

Back

A line that divides a figure into two mirror-image halves.

Front

What is the angle of rotation?

Back

The degree measure of the turn in a rotation transformation.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a figure over a line, while a rotation turns it around a point.

Front

How do you determine the direction of rotation?

Back

By specifying clockwise or counterclockwise from the fixed point.

Front

What is the result of a 180-degree rotation about the origin?

Back

The figure is turned upside down, with each point moving to the opposite side of the origin.

Front

What is the effect of a translation of (3, -2)?

Back

The figure moves 3 units to the right and 2 units down.
