Which statement correctly describes the relationship between the triangles? △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the y-axis and a translation 3 units down, which are both rigid motions.

△PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the y-axis and a reflection across the x-axis, which are both 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 90° counterclockwise rotation about the origin and a reflection across the y-axis, which are both rigid motions.
A pre-image and image on a coordinate plane. X-axis ranges from negative 8 to 9. Y-axis ranges from negative 8 to 8. Pre-image P Q R with point P at begin coordinate pair negative 6 comma 0 end coordinate pair, point R at begin coordinate pair negative 4 comma 3 end coordinate pair, point Q at begin coordinate pair negative 2 comma 0 end coordinate pair. Image P Q R with point P at begin coordinate pair 2 comma 0 end coordinate pair, point Q at begin coordinate pair 6 comma 0 end coordinate pair, point R at begin coordinate pair 6 comma negative 3 end coordinate pair.
