(n.) An equilateral parallelogram, or quadrilateral figure whose sides are equal and the opposite sides parallel. The angles may be unequal, two being obtuse and two acute, as in the cut, or the angles may be equal, in which case it is usually called a square.
(n.) A rhombohedron.
Example Sentences:
(1) They rose steeply from DIV 3 to 8 in rhomb- and diencephalon but not in mesencephalon.
(2) Other membranes of the same cell or of other cells display either FCC only, aligned and occasionally ordered in "rhombs," "lines" only, with a similar pattern, or randomly distributed FCC.
(3) The second type of crystal (not observed in serial sections) is found compatible with a rhomb-dodecahedron which indexes on a cubic cell with a equal to 9.6 nm.
(4) D. Perception of size: appreciation of shape in two dimentions: circle, triangle, square, cross, rhomb, appreciation of form in three dimensions: ball, column, cone, trignonal prism, cube.
(5) As models the square, the circle, the rhomb, and the equilateral triangle were used.
Rhombohedron
Definition:
(n.) A solid contained by six rhomboids; a parallelopiped.
Example Sentences:
(1) Other, less numerous typed include jointed otoconia, pure rhombohedrons and multifaceted, presumably immature forms.
(2) The multifaceted otoconia are most numerous, and the rhombohedrons proliferate, during childhon in the young adult, but saccular otoconia are the larger.
(3) On the root surface, however, these areas decreased remarkably; the shapes changed from pseudocubes into rhombohedrons and rugged rocky structures, while their sizes were smaller and the Mg content decreased.
(4) For the elongated otoconia (hexagonal prism) different parameters were measured: (1) the mean cleavage angle value of the terminal rhombohedron was 102 (SD 0.65), which was independent of the fetal age; (2) large and short axes show a linear growing law in function of the fetal age, and (3) the otoconial volume grows following a quadratic law.
(5) These include multifaceted, transitional and rounded body forms, some variant otoconia and a few rhombohedrons.
(6) The first type is the most frequent and is interpreted as a rhombohedron with a base, the ortho-hexagonal unit-cell edges being a equal to 18.9 nm, c equal to 23.0 nm.
