Consecutive angles are supplementary . Diagonals bisect each other. Opposite sides are congruent. REAL LIFE EXAMPLE PROPERTIES Opposite sides are parallel and congruent. The diagonals bisect each other. The diagonals are congruent. REAL LIFE EXAMPLE PROPERTIES Opposite angle of a rhombus have equal measures. The diagonals are congruent. Its diagonals bisect opposite angles. When they bisect each other its at a right angle. REAL LIFE EXAMPLE PROPERTIES The diagonals of a square bisect each other and meet at 90 ˚. Opposite sides are both parallel and equal. The diagonals of a square bisect its angles and they are also perpendicular. Diagonals are equal. REAL LIFE EXAMPLE PROPERTIES Quadrilaterals that have one set oppesite sides that are parallel REAL LIFE EXAMPLE PROPERTIES Quadrilaterals with one set of opposites are parallel. Two sides are congruent. REAL LIFE EXAMPLE Properties Opposite angle are equal. Consecutive angle are supplementary. Diagonals bisect each other. Opposite sides are congruent and parallel. The diagonals are congruent. Opposite sides of a rhombus have equal measures. Diagonals bisect opposite angles. Quads Diagonals bisect opposite angles. When they bisect each other is at a right angle. Diagonals of a square bisect each other and meet at 90 ̊ Opposite sides are both parallel and equal the diagonals of a square bisect its angles and they are also perpendicular. Diagonals are equal. Quadrilaterals that have one set opposite sides that are parallel. Two sides are congruent. If both pairs of opposite sides are quadrilateral are congruent, then the quadrilateral is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
