Select the statement about reflection that is not true.

• A reflection is a type of transformation that flips a figure over a line.

• The line of reflection acts as a mirror and creates an image that matches the pre-image in size and shape but is reversed.

• A reflection preserves the size and shape of an object.

• After a reflection, the original figure and its image are always parallel to each other.

Which of the following describes the rotation shown?

• 1. △S’T’U’ is a 90° rotation about the origin of △STU.

• 1. △S’T’U’is a 180° rotation about the origin of △STU.

• 1. △S’T’U’ is a 270° rotation about the origin of △STU.

• 1. △S’T’U’ is a 360° rotation about the origin of △STU.
