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′ ?

a.) △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.
b.) △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.
c.) △pqr is not congruent to △p′q′r′ because there is no sequence of rigid motions that maps △pqr to △p′q′r′
.
d.) △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.
