The figure shows lines r, n, and p intersecting to form angles 1, 2, 3, 4, 5, and 6. All 3 lines lie in the same plane. Based on the figure, which of the individual statements would provide enough information to conclude that line r is perpendicular to line p ? Select all that apply. M∠4 + M∠5 = 60° M∠3 = M∠6 M∠6 = 90° M∠1 + M∠6 = 90° M∠5 + M∠4 = 90° M∠2 = 90°
