Rigid Transformations

Front

What is the mathematical term for the line that you reflect a shape over?

Back

Line of reflection

Front

What is the transformation called when a shape is flipped over a line?

Back

Reflection

Front

What is the transformation called when a shape is turned around a fixed point?

Back

Rotation

Front

What are the three types of rigid transformations?

Back

Translations, rotations, and reflections

Front

What is the term for moving a shape without rotating or flipping it?

Back

Translation

Front

What happens to the size and shape of a figure during a rigid transformation?

Back

The size and shape remain unchanged.

Front

If a shape is reflected across the y-axis, what happens to its coordinates?

Back

The x-coordinates change sign, while the y-coordinates remain the same.

Front

What is the result of rotating a shape 90 degrees clockwise?

Back

The coordinates of the points change according to the rotation rules.

Front

What is the difference between a reflection and a rotation?

Back

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

Front

In a reflection, what is the relationship between the original shape and its image?

Back

They are congruent and mirror images of each other.
