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 __________ is a directed line segment that has both length and direction.  It is used when performing translations off the coordinate plane.

• vector
• rigid motion
• magnitude
• Gru

A rotation always moves _____________________ unless otherwise stated.

• clockwise
• counterclockwise
• sideways
• backwards
