The opposite angles of a parallelogram are equal. The consecutive angles of a parallelogram are supplementary. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram bisects it into two congruent triangles.
THEOREM: If a quadrilateral is a parallelogram, it has 2 sets of opposite angles congruent. THEOREM: If a quadrilateral is a parallelogram, it has consecutive angles which are supplementary. THEOREM: If a quadrilateral is a parallelogram, it has diagonals which bisect each other.
Parallelogram consecutive angles theorem: Consecutive angles of a parallelogram are supplementary. Theorem 1: Opposite angles of a parallelogram are equal. Given: PQRS is a parallelogram. To prove: ∠ P = ∠ R and ∠ Q = ∠ S. Proof: In the parallelogram PQRS, diagonal PR is dividing the parallelogram into two triangles. Also, PQ || SR and QR || PS.
