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)


Conjectures1
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)
