The coordinates of the vertices of △PQR are P(−3, 4), Q(−3, 1), and R(−1, 1). The coordinates of the vertices of △P′Q′R′ are P′(−6, −5), Q′(−6, −1), and R′(−4, −1). Which statement correctly describes the relationship between △PQR and △P′Q′R′?

△PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the x-axis followed by a translation 3 units to the left, which is a sequence of rigid motions.

△PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a translation 3 units to the left followed by a reflection across the x-axis, which is a sequence of rigid motions.

△PQR is not congruent to △P′Q′R′ because there is no sequence of rigid motions that maps △PQR to △P′Q′R′.

△PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the x-axis followed by a translation 1 unit down, which is a sequence of rigid motions.
