What's the difference between parallelogram and rhombus?

Parallelogram


Definition:

  • (n.) A right-lined quadrilateral figure, whose opposite sides are parallel, and consequently equal; -- sometimes restricted in popular usage to a rectangle, or quadrilateral figure which is longer than it is broad, and with right angles.

Example Sentences:

  • (20) Such reports were made in the presence or absence of various types of visual, geometric surrounds (squares, triangles, crosses, or parallelograms).

Rhombus


Definition:

  • (n.) Same as Rhomb, 1.

Example Sentences:

  • (1) The calculation has shown that the rounding of one of the angles of interference rhombus and its displacement towards the centre of the picture speak about either a functional deficiency of a muscle inserted into the eye ball in this place or about displacement of the point of its insertion from the limbus along the meridian of its action; displacement of one the angles of interference rhombus from the meridian speaks about displacement of the point of efforts exertion of the corresponding muscle into the same direction.
  • (2) Examination of eyes in a polarized light in 108 children and 24 adults with congenital concomitant convergent squint with a vertical component has shown displacement of internal angles of the rhombus of interference pictures from the horizontal axis, this speaking about anomaly of internal rectus muscles insertion.
  • (3) Antemolar rhombus (the anterior part of the intermolar palate) of adult Wistar rat was employed as experimental area.
  • (4) n. from Pungitius pungitius is near to M. paragasterostei but differs from it by the rhombus form of the spore, by less dimension of polar capsules.
  • (5) The figure of tetrahedron is formed in certain species of Plectus and in Tobrilus gracilis at the stage of 4 blastomeres rather than a rhombus which is formed in most highly organized nematodes.
