Transformations Review

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 of the following is NOT a rigid transformation?

Back

Dilation is NOT a rigid transformation because it changes the size of the figure.

Front

How do you translate a figure?

Back

To translate a figure, you move it a certain distance in a specified direction without changing its shape or orientation.

Front

What are the coordinates of point A' after a 90° counterclockwise rotation of point A(3, 5) about the origin?

Back

The coordinates of A' would be (-5, 3).

Front

What is the result of rotating a figure 180°?

Back

Rotating a figure 180° results in a figure that is upside down from its original position.

Front

What is a reflection in geometry?

Back

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

Front

If triangle ABC is translated left two and up nine, what are the new coordinates of point A(4, 2)?

Back

The new coordinates of point A would be (2, 11).

Front

What is the difference between rotation and reflection?

Back

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

Front

What does it mean to rotate a figure 90° clockwise?

Back

To rotate a figure 90° clockwise means to turn it a quarter turn to the right around a point.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.
