Notice how the four sides remain the same length and the opposite sides remain parallel. A rhombus is actually just a special type of parallelogram.
Traditionally, in two-dimensional geometry, a rhomboid is a parallelogram in which adjacent sides are of unequal lengths and angles are non-right angled.A parallelogram with sides of equal length (equilateral) is a rhombus but not a rhomboid. parallelogram with right angled corners is a rectangle but not a rhomboid. The term rhomboid is now more often used for a parallelepiped, a solid figure with six faces in which each face is a parallelogram and pairs of opposite faces lie in parallel planes. Some crystals are formed in three-dimensional rhomboids.
