  5. Conjectures • The diagonals of a parallelogram divide the parallelogram into two congruent triangles. (Atticus) • If a quadrilateral has two pairs of equal opposite angles, it is a parallelogram. (Eva) • All rectangles are parallelograms. • A square’s diagonals bisect the square’s angles. (Erin & Megan) • A parallelogram’s diagonals create congruent “opposite” triangles.(Graden / Kesh) • If two opposite sides of one parallelogram equal two opposite sides of another, the two parallelograms are congruent. (Nima)

  6. Conjectures • If both pairs of opposite sides of one parallelogram equal both pairs of opposite sides of another, the two parallelograms are congruent. (Nima, revised) • Any two consecutive angles of a parallelogram are supplementary.(Sydney)
