A quadrilateral with no sides parallel.
- ‘He has invented the trisosceles trapezoid (or trapezium as we say in the UK).’
- ‘The bold monochrome panels in other works, such as the juxtaposed trapezoids in the Birds Over Loop pieces, are reminiscent of Sean Scully's paintings.’
- ‘It is not an easy show: a dozen works on paper, single coloured trapezoids, subtle curves and rhomboids, hung sparely in a stark white interior.’
- ‘It is also relatively easy to make, as long as you don't get too fussed about perfect trapezoids of bread and the delicate art of construction.’
- 1.1North American A quadrilateral with one pair of sides parallel.Compare with trapezium
- ‘For example, Angel consists of three layers of open triangles, trapezoids, parallelograms and pentagons, once again made of wood.’
- ‘The key elements of our total approach include measurements, models, and data, which are represented by the black squares, trapezoids, and ellipses respectively.’
- ‘He arranges thin rectangles, squares, triangles and trapezoids in complex patterns on the wall.’
- ‘With their vast knowledge of geometry, they were able to correctly calculate the areas of triangles, rectangles, and trapezoids and the volumes of figures such as bricks, cylinders, and pyramids.’
- ‘Wood blinds, meanwhile, can fit a variety of applications, including quarter arches, full arches, angles, trapezoids, hexagons and triangles.’
A small carpal bone in the base of the hand, articulating with the metacarpal of the index finger.
- ‘Climbing mostly builds muscles that pull (forearms, lats, trapezoids, biceps) while demanding less of those that push (shoulders, pectorals, triceps).’
- ‘Complete dislocation of the acromioclavicular joint with avulsion of the trapezoid and deltoid muscle results in a decrease in upper extremity strength.’
- ‘The distal row of carpals includes the hamate, capitate, trapezium, and trapezoid, which are closely approximated to the metacarpals.’
- ‘During surgery, we observed partial or complete detachment of the trapezoid and deltoid muscles from the lateral clavicle in all patients.’
- ‘A mass of muscle would pop up: deltoids would ripple, trapezoids bunch and gloots clench.’
Early 18th century: from modern Latin trapezoides, from late Greek trapezoeidēs, from trapeza table (see trapezium).
