• Special quadrilaterals are quadrilaterals that have certain properties.
• Examples of special quadrilaterals are found in trapezoids, parallelograms, rhombi, rectangles, and squares.
• Opposite sides of parallelograms are parallel.
• Opposite sides are congruent.
• Diagonals of a parallelogram bisect each other.
• Consecutive angles are supplementary.
• A rhombus is a parallelogram.
• The diagonals of a rhombus are perpendicular and bisect the angles.
• A rectangle is a parallelogram.
• The diagonals of a rectangle are congruent.
• Each angle is 90.
• A square is a parallelogram, a rhombus, and a rectangle.
• Diagonals of a square bisect each other, are perpendicular, are congruent, and bisect the angles.
