What statements about dilations are true? Check all that apply.A dilation preserves side lengths.A dilation preserves angle measures.A dilation preserves the direction that the shape faces.A dilation is a type of isometric transformation. The side lengths of a dilated image are proportional to the side lengths of the pre-image.

A dilation multiplies every side length by the same scale factor, so side lengths may change but remain proportional; this makes E true and A false. It preserves angle measures and, for the usual positive scale factor, the shape’s orientation, so B and C are true. It is not an isometric transformation because an isometry preserves side lengths, so D is false.
