A person talking on a phone moves the phone to her other ear. What transformation best describes how the phone moved?

• A translation, because the phone moved from one side to the other and is facing in the same direction.

• A reflection, because the phone moved an equal distance across the person’s head and is facing the other direction

• A rotation, because the phone was facing a different direction and is now facing the opposite direction.

• A reflection, because the phone moved the same distance across the person’s head and is facing the same direction.
