Which statement best explains whether △JKL is congruent to △MNP?

△JKL is congruent to △MNP because △JKL can be mapped to △MNP by a reflection across the y-axis.

​△JKL is congruent to △MNP because △JKL can be mapped to △MNP by a reflection across the x-axis followed by a rotation of 180° about the origin.

△JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.

△JKL is not congruent to △MNP because there is no sequence of rigid motions that maps △JKL to △MNP.
