Sphenoid :: Sphenoid (n.) A wedge-shaped crystal bounded by four equal isosceles triangles. It is the hemihedral form of a square pyramid.

Triangulation :: Triangulation (n.) 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 the several points connected by them..

Triangular :: Triangular (a.) Having three angles; having the form of a triangle.

Rib :: Rib (n.) In Gothic vaulting, one of the primary members of the vault. These are strong arches, meeting and crossing one another, dividing the whole space into triangles, which are then filled by vaulted construction of lighter material. Hence, an imitation of one of these in wood, plaster, or the like..

Subcontrary :: Subcontrary (a.) Having, or being in, a contrary order; -- said of a section of an oblique cone having a circular base made by a plane not parallel to the base, but so inclined to the axis that the section is a circle; applied also to two similar triangles when so placed as to have a common angle at the vertex, the opposite sides not being parallel..

Oblique-angled :: Oblique-angled (a.) Having oblique angles; as, an oblique-angled triangle..

Birectangular :: Birectangular (a.) Containing or having two right angles; as, a birectangular spherical triangle..

Hypothenuse :: Hypothenuse (n.) The side of a right-angled triangle that is opposite to the right angle.

Self-conjugate :: Self-conjugate (a.) Having the two things that are conjugate parts of the same figure; as, self-conjugate triangles..

Equivalent :: Equivalent (a.) Equal in measure but not admitting of superposition; -- applied to magnitudes; as, a square may be equivalent to a triangle..

Pentacle :: Pentacle (n.) A figure composed of two equilateral triangles intersecting so as to form a six-pointed star, -- used in early ornamental art, and also with superstitious import by the astrologers and mystics of the Middle Ages..

Pyramid :: Pyramid (n.) The game of pool in which the balls are placed in the form of a triangle at spot.

Cathetus :: Cathetus (n.) One line or radius falling perpendicularly on another; as, the catheti of a right-angled triangle, that is, the two sides that include the right angle..

Acute-angled :: Acute-angled (a.) Having acute angles; as, an acute-angled triangle, a triangle with every one of its angles less than a right angle..

Side :: Side (n.) The margin, edge, verge, or border of a surface; especially (when the thing spoken of is somewhat oblong in shape), one of the longer edges as distinguished from the shorter edges, called ends; a bounding line of a geometrical figure; as, the side of a field, of a square or triangle, of a river, of a road, etc..
