9-1 TRANSLATIONSObjective: To identify rigid motions. To find translation images of figures.

Vocabulary• Transformation: results in a change in position, shape, or

size of the figure.• preimage: original figure in a transformation• Image: resulting figure in transformation• Rigid motion: transformation that preserves distance and

angle measure

Problem 1• Does the transformation appear to be a rigid motion?
