Examine the diagram. Parallel lines c and d are cut by transversals e and f. At the intersection of lines c, e, and f, clockwise from top left, the angles are 4, 5, 6, blank, 3, blank. At the intersection of lines d and f, the angles are blank, 1, blank, blank, At the intersection of lines e and d, the angles are 2, blank, blank, blank.

Use the diagram to complete these statements.
