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.

    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.

  2. (Mus.) 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. (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.

  5. (Astron.)

      Triangle spider (Zo["o]l.), a small American spider ( Hyptiotes Americanus) of the family Ciniflonid[ae], 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.

Triangle

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted △ABC.

In Euclidean geometry any three points, when non-collinear, determine a unique triangle and a unique plane (i.e. a two-dimensional Euclidean space). This article is about triangles in Euclidean geometry except where otherwise noted.

Triangle (1981 TV series)

Triangle was a BBC Television soap opera in the early 1980s, set aboard a North Sea ferry which sailed from Felixstowe to Gothenburg and Gothenburg to Amsterdam. A third imaginary leg existed between Amsterdam and Felixstowe to justify the programme title, but this was not operated by the ferry company. The show ran for three series before being cancelled, but is still generally remembered as "some of the most mockable British television ever produced". The scripts involved clichéd relationships and stilted dialogue, making the show the butt of several jokes - particularly on Terry Wogan's morning Radio 2 programme - which caused some embarrassment to the BBC.

In 1992, the BBC screened TV Hell, an evening of programming devoted to the worst television had to offer, and the first episode of Triangle was broadcast as part of the line-up.

The ferry used in the first series was the Tor Line's . In the second and third series this was replaced by the DFDS vessel Dana Anglia (DFDS having acquired Tor Line by this time) probably because she had a less intensive schedule and the longer time she spent in port made on-board filming easier.

Triangle (The X-Files)

"Triangle" is the third episode of the sixth season of the American science fiction television series The X-Files and premiered on the Fox network on November 22, 1998. Written and directed by series creator Chris Carter, "Triangle" is a " Monster-of-the-Week" episode, a stand-alone plot which is unconnected to the overarching mythology of The X-Files. "Triangle" earned a Nielsen household rating of 10.8, being watched by 18.20 million viewers in its initial broadcast. The episode generally received positive reviews, with many critics commenting on the episode's unique directing style.

The show centers on FBI special agents Fox Mulder ( David Duchovny) and Dana Scully ( Gillian Anderson), who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, and the skeptical Scully has been assigned to debunk his work. However, the two have developed a close friendship. In this episode, Mulder races to a luxury passenger liner which has mysteriously appeared on the edge of the Bermuda Triangle. Once there, he realizes he has traveled back in time to September 3, 1939—the outbreak of World War II. German soldiers have boarded the ship in search of "Thor's Hammer", something that could ensure victory in the coming conflict. Meanwhile, Scully, after being informed of Mulder's disappearance by The Lone Gunmen, rushes through the J. Edgar Hoover Building, looking for someone who can help find her missing partner.

"Triangle" is notable for the unique style in which it was filmed. Inspired by the 1948 Alfred Hitchcock film Rope, with many shots filmed and edited to appear as one single take. In addition, "Triangle" features the main and recurring cast members such as Anderson, William B. Davis, Chris Owens, James Pickens Jr. and Mitch Pileggi, who played their contemporary characters as well as distinctly different characters from 1939 on board the luxury liner. Several of the episode's themes have been critically examined—the concept of "dream-nazis", the appearance of modern characters portraying those from the past, and the ramification that the entire episode was a dream.

Triangle (2007 film)

Triangle is a 2007 Hong Kong action film produced and directed by Tsui Hark, Ringo Lam, and Johnnie To. This was the final film directed or co-directed by Ringo Lam, who has since retired as a film director. The film's title refers to both the acclaimed trio of filmmakers and to the uneasy brotherhood of the film's three protagonists. Triangle tells one story which is told in three thirty-minute segments, independently helmed by the three directors. It stars Louis Koo, Simon Yam and Sun Honglei as a group of friends who uncover a hidden treasure that quickly draws attention among others. The film's tagline is "Temptation. Jealousy. Destiny." Each word is often associated with the segments that appear in chronological order.

The first Hong Kong film made in a frame story format, Triangle had each director take charge of a film segment, bringing in their own production team and screenwriters to continue the story set in motion by the previous director. Critics made easy notice of the lack of continuity in between each segment, since the trio of directors did not share their scripts together while discussing the concepts.

Triangle was screened out of competition at the 2007 Cannes Film Festival. It was later released in China on 1 October 2007, which was one month before its theatrical Hong Kong release.

Triangle (chart pattern)

Triangles are commonly found in the price charts of financially traded assets (stocks, bonds, futures, etc.). The pattern derives its name from the fact that it is characterized by a contraction in price range and converging trendlines, thus giving it a triangular shape.

Triangle patterns can be broken down into three categories: the ascending triangle, the descending triangle, and the symmetrical triangle. While the shape of the triangle is significant, of more importance is the direction that the market moves when it breaks out of the triangle. Lastly, while triangles can sometimes be reversal patterns—meaning a reversal of the prior trend—they are normally seen as continuation patterns (meaning a continuation of the prior trend).

Triangle (Perfume album)

Triangle (The Beau Brummels album)

Triangle is the fourth studio album by American rock band The Beau Brummels. Produced by Lenny Waronker and released in July 1967, it was the band's first album to include songs that vocalist Sal Valentino and guitarist Ron Elliott composed together. The band incorporated fantasy elements and surreal characters into the album's song titles and lyrics, and worked with a variety of session musicians to create Triangle's psychedelic musical style. The Beau Brummels were reduced to a trio—Valentino, Elliott, and Ron Meagher—at the time Triangle was recorded, as former group members Don Irving (guitars) and John Petersen (drums) left the band following the release of the group's previous album, Beau Brummels '66.

Triangle reached number 197 on the Billboard 200 albums chart and received mostly positive reviews; critics commended Elliott as a songwriter and compared Valentino's vocals to those of Bob Dylan. The single " Magic Hollow" was ranked one of "The 100 Greatest Psychedelic Classics" in a 1997 issue of Mojo magazine. Warner Japan released this album as WPCP-5252 in 1993. Collectors' Choice Music reissued the album in 2002.
