Examples
“Rosse himself writing to Professor Nichol, in 1846, "I may safely say there can be little, if any, doubt as to the resolvability of the nebula; -- all about the trapezium is a mass of stars, the rest of the nebula also abounding with stars, and exhibiting the characteristics of resolvability strongly marked.”
“Orionis, also called the trapezium of Orion) is in itself the most striking multiple star in the whole heavens.”
“But for better or worse, they thrived down here, especially in what is known as Cajun country, the geocultural trapezium whose points are New Orleans, Houma, Cameron, and Lafayette.”
“I just borrowed it to refer to the shape of the basins in section -- cones with their apices cut off or a 3-sides-equal trapezium, exactly similar to the ones you see in the diagrams above, though it would be serrated because of the stairs.”
“It was the size of — and as oddly shaped a trapezium as — a bad West Village studio.”
“The remainder of the trapezium formed the garden, which was much lower than the level of the Rue Polonceau, which caused the walls to be very much higher on the inside than on the outside.”
“In this manner they crossed the inner trapezium of the barricade.”
“It was in this sort of fold in the interior trapezium of the barricade, that Eponine had breathed her last.”
“These four streets surrounded this trapezium like a moat.”
