Rhombus Conjectures


A rhombus is a parallelogram with sides that are equal in length. The Parallelogram Conjectures tell us that the diagonals of a parallelogram bisect each other. Therefore, the diagonals of a rhombus must also bisect each other. But there are two other special properties about the diagonals of a rhombus. The diagonals are perpendicular to each other, and they bisect the each of the interior angles of the rhombus.

The precise statement of the conjecture is:

Conjecture (Rhombus Conjectures ): The diagonals of a rhombus are perpendicular to each other. The diagonals of a rhombus bisect the angles of the rhombus.
