| triangle | 1. <geometry> A figure bounded by three lines, and containing three angles. A triangle is either plane, spherical, or curvilinear, according as its sides are straight lines, or arcs of great circles of a sphere, or any curved lines whatever. A plane triangle is designated as scalene, isosceles, or equilateral, according as it has no two sides equal, two sides equal, or all sides equal; and also as right-angled, or oblique-angled, according as it has one right angle, or none; and oblique-angled triangle is either acute-angled, or obtuse-angled, according as all the angles are acute, or one of them obtuse. The terms scalene, isosceles, equilateral, right-angled, acute-angled, and obtuse-angled, are applied to spherical triangles in the same sense as to plane triangles. 2. An instrument of percussion, usually made of a rod of steel, bent into the form of a triangle, open at one angle, and sounded by being struck with a small metallic rod. 3. A draughtsman's square in the form of a right-angled triangle. 4. A kind of frame formed of three poles stuck in the ground and united at the top, to which soldiers were bound when undergoing corporal punishment, now disused. 5. <astronomy> A small constellation situated between Aries and Andromeda. A small constellation near the South Pole, containing three bright stars. <zoology> Triangle spider, a small American spider (Hyptiotes Americanus) of the family Ciniflonidae, living among the dead branches of evergreen trees. It constructs a triangular web, or net, usually composed of four radii crossed by a double elastic fibre. The spider holds the thread at the apex of the web and stretches it tight, but lets go and springs the net when an insect comes in contact with it. Origin: L. Triangulum, fr. Triangulus triangular; tri- (see Tri-) + angulus angle: cf. F. Triangle. See Angle a corner. Source: Websters Dictionary (01 Mar 1998) |

| triangle bandage | <orthopaedics> A cloth (muslin) bandage in the shape of an equilateral triangle. Two triangle bandages can be made by cutting a 36-40 inch cloth square diagonally corner to corner. The triangle bandage is an excellent first aid dressing for scalp wounds and can also be used as a shoulder sling. (19 Jan 1998) |

| triangle |
The triangle is an idiophonic musical instrument of the percussion family. It is a bar of metal, usually steel in modern instruments, bent into a triangle shape. One of the angles is left open, with the ends of the bar not quite touching - this causes the instrument to be of indeterminate pitch. It is usually suspended from one of the other corners by a piece of thin wire or gut, leaving it free to vibrate. It is usually struck with a metal beater, giving a high-pitched, ringing tone. ...
