Which statements are correct regarding the properties of trapezoids? Check all that apply.The diagonals of an isosceles trapezoid are congruent.The bases of a trapezoid are parallel.The adjacent sides of a trapezoid are congruent.Base angles of a trapezoid are congruent.The diagonals of a trapezoid are perpendicular.

An isosceles trapezoid has congruent diagonals, so statement A is correct. A trapezoid’s bases are parallel by definition, so statement B is also correct. The legs (adjacent sides), base angles, and diagonals are not necessarily congruent or perpendicular in every trapezoid; some of those properties may hold in special cases.
