What's the difference between rhombus and trapezoid?

Rhombus


Definition:

  • (n.) Same as Rhomb, 1.

Example Sentences:

Trapezoid


Definition:

  • (n.) A plane four-sided figure, having two sides parallel to each other.
  • (n.) A bone of the carpus at the base of the second metacarpal, or index finger.
  • (a.) Having the form of a trapezoid; trapezoidal; as, the trapezoid ligament which connects the coracoid process and the clavicle.
  • (a.) Of or pertaining to the trapezoid ligament; as, the trapezoid line.
