  2. Definition: A Parallelogram is a quadrilateral where BOTH pairs of opposite sides are parallel • In PQRS, PQ SR and QR PS P Q R S

  3. Theorem: If a quadrilateral is a parallelogram, then its opposite sides are congruent • In PQRS, PQ = SR and QR = PS P Q R S

  4. Theorem: If a quadrilateral is a parallelogram, then its opposite angles are congruent • In PQRS, <P = <R and <Q = <S P Q R S

  5. Theorem: If a quadrilateral is a parallelogram, then its consecutive angles are supplementary • In PQRS, xo + yo = 180o 180o P Q xo yo 180o 180o yo xo R S 180o

  6. Theorem: If a quadrilateral is a parallelogram, then diagonals bisect each other • In PQRS, QM = MS and PM = MR 180o P Q 180o M 180o R S 180o
