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.

Harper completed a transformation of pre-image ABCD that results in the image A’B’C’D’ as shown. Which statements about the relationship between the pre-image and the image can Josh concluded are true?

• The image is both congruent and similar to the preimage because all congruent figures are also similar figures.

• The image is NOT congruent to the preimage because rotations change the length of the line segments and angle measures.

• The image is similar to the preimage because the corresponding sides have a ratio of 1:1.

• The image is NOT similar to the preimage because the areas of the figures are equal.

• The image is congruent to the preimage because the image is the result of a rotation.
