The document defines and provides properties of a rhombus. A rhombus is a four-sided shape where all sides have equal length and opposite sides are parallel. The properties include that the diagonals bisect each angle, opposite angles are equal, the sum of the interior angles is 360 degrees, and opposite sides are parallel. Any two consecutive internal angles are supplementary. The area formula is A=BH/2 and the perimeter formula is P=LW.
