The transversal part of a church, which crosses at right angles to the greatest length, and between the nave and choir. In the basilicas, this had often no projection at its two ends. In Gothic churches these project these project greatly, and should be called the arms of the transept. It is common, however, to speak o…

hrough the foci. -- Transverse partition (Bot.), a partition, as of a pericarp, at right angles with the valves, as in the siliques of mustard.

A figure bounded by three lines, and containing three angles.

Having three angles; triangular.

Having three angles; having the form of a triangle.

To divide into triangles; specifically, to survey by means of a series of triangles properly laid down and measured.

The series or network of triangles into which the face of a country, or any portion of it, is divided in a trigonometrical survey; the operation of measuring the elements necessary to determine the triangles into which the country to be surveyed is supposed to be divided, and thus to fix the positions and distances of…

Having, or characterized by, three unequal axes intersecting at oblique angles. See the Note under crystallization.

A figure having three angles; a triangle.

Having three angles, or corners; triangular; as, a trigonal stem, one having tree prominent longitudinal angles.

Having horns with three angles, like those of some species of goats.

like. These lines, or the lengths of them, are trigonometrical functions of the arcs and angles to which they belong. -- Trigonometrical survey. See under Survey.

That branch of mathematics which treats of the relations of the sides and angles of triangles, which the methods of deducing from certain given parts other required parts, and also of the general relations which exist between the trigonometrical functions of arcs or angles.

ing three sides or faces; thus, a trihedral angle is a solid angle bounded by three plane angles. [Written also triedral.]

s; thus, a triquadrantal triangle is one whose three sides are quadrants, and whose three angles are consequently right angles.

Three sided, the sides being plane or concave; having three salient angles or edges; trigonal.

Having three right angles. See Triquadrantal.

An instrument used by carpenters, joiners, etc., for laying off right angles off right angles, and testing whether work is square.

A level passage driven across the measures, or at right angles to veins which it is desired to reach; -- distinguished from the drift, or gangway, which is led along the vein when reached by the tunnel. Tunnel head (Metal.), the top of a smelting furnace where the materials are put in. -- Tunnel kiln, a limekiln in wh…

A frame consisting of two bars crossing each other at right angles and turning on a post or pin, to hinder the passage of beasts, but admitting a person to pass between the arms; a turnstile. See Turnstile, 1. I move upon my axle like a turnpike. B. Jonson.
