Which quadrilateral has diagonals that are always perpendicular bisectors of each other?

• trapezoid

• parallelogram

Which theorem correctly justifies the statement above the image?

• If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular.

• If two lines are perpendicular, then they intersect to form four right angles.

• If two sides of two adjacent acute angles are perpendicular, then the angles are complementary.

• No theorem justifies the statement.
