Two students are trying to show that the two figures are congruent. the first student decides to map defg to rstu using a rotation of 180° about the origin, followed by the vertical translation (x, y) → (x, y + 4). the second student uses a reflection across the x-axis, followed by the vertical translation (x, y) → (x, y + 4), followed by a reflection across the y-axis. are both students correct, is only one student correct, or is neither student correct? a rotation of 180° about the origin is the same as a reflection across both axis/y-axis/x-axis. both students/the first student/the second student/neither students is/are correct
