Two transformations of quadrilateral ABCD are shown below. Identify which transformation is a rigid motion and describe that rigid motion. ​ (a)   is/are a rigid transformation because ABCD maps onto A′B′C′D′ with ​ (b)  

• Only Transformation 2

• Only Transformation 1

• Both Transformation 1 and Transformation 2

• rotation of 60 degrees about point P

• reflection across line that passes through point P

• translation that maps point D to point P

Each diagram shows a pre-image and an image. Match graph with the descriptions of the rigid motion or sequence of rigid motions that transformed the pre-image to its image.

• Rotate 90 degrees clockwise around the point (-1, 2)

• 
• Reflected over the line y = x

• 
• (x, y) -> (x+3, y-2)

• 
• Rotate 180 degrees around the point (0, 0)
