Assume that lines c and b are parallel. complete each statement. in terms of m and a number in degrees, p = ? in terms of m and number in degrees, n = ? therefore, in terms of m, n = ? these statements prove which theorem? a) p = 90 - m; n = 90 - m; n = p; if parallel lines have a transversal, then vertical angles are congruent. b) p = 90 - m; n = 90 - m; n = p; if parallel lines have a transversal, then corresponding angles are congruent. c) p = 90 - m; n = 90 - m; n = p; if parallel lines have a transversal, then alternate interior angles are congruent. d) p = 90 - m; n = 90 - m; n = p; if parallel lines have a transversal, then same side interior angles are congruent.
