In Exercises 29 to 35, complete a formal proof. 29. The diagonals of an isosceles trapezoid are congruent. 30. The median of a trapezoid is parallel to each base. 31. If two consecutive angles of a quadrilateral are supplementa- ry, the quadrilateral is a trapezoid. 32. If two base angles of a trapezoid are congruent, the trapezoid is an isosceles trapezoid. 33. If three parallel lines intercept congruent segments on one transversal, then they intercept congruent segments on any transversal.
