Which statement is true?

• Rectangle WXYZ is congruent to W'X'Y'Z' because at least one nonrigid transformation is used to transform rectangle WXYZ since the side lengths of the rectangle are not preserved.

• Rectangle WXYZ is congruent to W'X'Y'Z' because only rigid transformations are used to transform rectangle WXYZ since the side lengths of the rectangle are preserved.

• Rectangle WXYZ is congruent to W'X'Y'Z' because at least one nonrigid transformation is used to transform rectangle WXYZ since the side lengths of the rectangle are NOT preserved.

• Rectangle WXYZ is NOT congruent to W'X'Y'Z' because only rigid transformations are used to transform rectangle WXYZ since the side lengths of the rectangle are preserved.
