True or False:  A Rotation is a type of 'Rigid Transformation'.

• True:  A Rotation retains the pre-image's shape and size.

• False: A Rotation enlarges the pre-image's shape.

If Δ ABC is rotated 90° clockwise about the origin, what will be the new coordinates of vertex B?

• ( 4, 1 )

• ( 1, 4 )

• ( -1, -4 )

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.

Pentagon P and pentagon Q, shown in the picture, are congruent. Which sequence could be used to transform pentagon P to pentagon Q?

• A translation four units left and then a reflection over the x-axis.

• A reflection over the y-axis and then a translation seven units down.
