Which transformation is NOT a rigid motion (the size changes)?

• reflection
• rotation
• dilation
• translation

When performing a translation, or slide, you _____ the numbers to your x and y value in the point. 

• add
• subtract
• multiply
• divide

A rotation always moves _____________________ unless otherwise stated.

• clockwise
• counterclockwise
• sideways
• backwards

The following is an example of which transformation ...

• Rotation

• reflection in the x-axis

• reflection in the y-axis

• translation

What are the series of rigid motions that would map ∆ABC onto ∆A''B''C''?

• a reflection followed by a rotation
• a reflection followed by a translation
• a translation followed by a rotation
• a translation followed by a reflection
