30. StatementReason 1. Given 4. Perpendicular segments form right angles 2. Given 3. Given 5. All right angles are congruent 6. Two adjacent angles that form a straight line are a linear pair 7. Linear pairs are supplementary 8. Supplements of congruent angles are congruent.

32. x y Since all four sides are congruent, quadrilateral MATH is a rhombus. Since the slopes of consecutive sides are not negative reciprocals, they are not perpendicular and do not form a right angle. Therefore, MATH is not a square.
