RHOMBUS

, is an oblique equilateral parallelogram; | on a quadrilateral figure, whose sides are equal and parallel, but the four angles not all equal, two of the opposite ones being obtuse, and the other two opposite ones acute.

The two diagonals of a Rhombus intersect at right angles; but not of a rhomboides.

As to the area of the Rhombus or rhomboides, it is found, like that of all other parallelograms, by multiplying the length or base by the perpendicular breadth.
