  Triangle \Tri"an`gle\, n. [L. triangulum, fr. triangulus
     triangular; tri- (see {Tri-}) + angulus angle: cf. F.
     triangle. See {Angle} a corner.]
     1. (Geom.) A figure bounded by three lines, and containing
        three angles.
        [1913 Webster]


  
     Note: 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.
           [1913 Webster]
  
     2. (Mus.) An instrument of percussion, usually made of a rod

        rod.
        [1913 Webster]
  
     3. A draughtsman's square in the form of a right-angled
        triangle.
        [1913 Webster]
  
     4. (Mus.) 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.
        [1913 Webster]
  
     5. (Astron.)
        (a) A small constellation situated between Aries and
            Andromeda.
        (b) A small constellation near the South Pole, containing
            three bright stars.
            [1913 Webster]
  
     {Triangle spider} (Zool.), 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 fiber. 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.
        [1913 Webster]
