Unit 1 Rigid Transformations Practice

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

Which transformations are considered rigid transformations?

Back

Translations, rotations, and reflections.

Front

What is the effect of a reflection across the x-axis on the coordinates (x, y)?

Back

The new coordinates will be (x, -y).

Front

What is the effect of a reflection across the y-axis on the coordinates (x, y)?

Back

The new coordinates will be (-x, y).

Front

What are the coordinates after a 90° clockwise rotation of point (x, y)?

Back

The new coordinates will be (y, -x).

Front

What are the coordinates after a 270° clockwise rotation of point (x, y)?

Back

The new coordinates will be (-y, x).

Front

Describe the transformation: Reflect across the x-axis and then rotate 90 degrees CCW.

Back

The figure will first be flipped over the x-axis and then rotated 90 degrees counterclockwise.

Front

What is the result of translating a point (x, y) up by 3 units?

Back

The new coordinates will be (x, y + 3).

Front

What is the result of rotating a point (x, y) 180 degrees around the origin?

Back

The new coordinates will be (-x, -y).

Front

If a figure is translated down 4 units, what is the transformation rule?

Back

The new coordinates will be (x, y - 4).
