The vertices of pentagon ABCDE are A(-4, 1), B(-1, 2), C(1, 5), D(0, 8), and E(-3, 6). The vertices of pentagon KLMNO are K(-8, 1), L(-2, 2), M(2, 5), N(0, 8), and O(-6, 6). A classmate named Seth says the figures are not congruent because a reflection cannot produce a congruent figure. Which response is the strongest?
