The coordinates of the vertices of △pqr are p(1, 4) , q(2, 2) , and r(−2, 1) . the coordinates of the vertices of △p′q′r′ are p′(−1, 4) , q′(−2, 2) , and r′(2, 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, which is a rigid motion. b) △pqr is congruent to △p′q′r′ because you can map △pqr to △p′q′r′ using a reflection across the y-axis, which is a rigid motion. c) △pqr is congruent to △p′q′r′ because you can map △pqr to △p′q′r′ using a translation 2 units to the left, which is a rigid motion. d) △pqr is not congruent to △p′q′r′ because there is no sequence of rigid motions that maps △pqr to △p′q′r′ .
