He coordinates of the vertices of △jkl are j(3, 0) , k(1, −2) , and l(6, −2) . the coordinates of the vertices of △j′k′l′ are j′(−3, 1) , k′(−1, 3) , and l′(−6, 3) . which statement correctly describes the relationship between △jkl and △j′k′l′ ? △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a translation 1 unit up followed by a reflection across the y-axis, which is a sequence of rigid motions. △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a reflection across the x-axis followed by a reflection across the y-axis, which is a sequence of rigid motions. △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions. △jkl is not congruent to △j′k′l′ because there is no sequence of rigid motions that maps △jkl to △j′k′l′.
