Opposite angles are always congruent in a(n)

• quadrilateral

• parallelogram

• trapezoid

• isosceles trapezoid

Consecutive angles are always supplementary in a

• quadrilateral

• triangle

• parallelogram

One way to prove that a quadrilateral is a parallelogram is to show that

• the diagonals arre congruent

• it has one pair of congruent sides

• it has one pair of parallel sides

• the diagonals bisect each other

Not all rectangles have

• consecutive angles that are supplementary

• diagonals that bisect each other

• diagonals that are congruent

• four congruent sides

Diagonals are always perpendicular in a

• rhombus

• rectangle

• parallelogram

• trapezoid
