Ind ! △def is rotated about point n to △d′e′f′ . which statements are true about the pre-image and image? select each correct answer. dn¯¯¯¯¯¯≅d′n′¯¯¯¯¯¯¯¯ all corresponding points on the image and pre-image are equidistant to point n. the image is the same size and shape as the pre-image. the corresponding side lengths in the image and the pre-image are not equal.

△DEF is rotated about point N to △D′E′F′.

A rotation is a transformation that turns a figure about a fixed point called the center of rotation. In your case the center of rotation is point N. A rotation is an isometric transformation: the original figure and the image are congruent. Main properties of rotation:

1) A rotation preserves lengths of segments.

2) A rotation preserves degrees of angles.

3) A rotation maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle.

Therefore, option C is true (because the original figure and the image are congruent) and option D is false (because the original figure and the image must be congruent).

All corresponding points on the image and pre-image are equidistant to point N. This option is true (because rotation preserves lengths of segments), thus, DN≅D'N'.
