Octagon 2 Download

A regular octagon has Schlfli symbol {8} [1] and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}. A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square.

Each side of a regular octagon subtends half a right angle at the centre of the circle which connects its vertices. Its area can thus be computed as the sum of eight isosceles triangles, leading to the result:

A skew octagon is a skew polygon with eight vertices and edges but not existing on the same plane. The interior of such an octagon is not generally defined. A skew zig-zag octagon has vertices alternating between two parallel planes.

A regular skew octagon is vertex-transitive with equal edge lengths. In three dimensions it is a zig-zag skew octagon and can be seen in the vertices and side edges of a square antiprism with the same D4d, [2+,8] symmetry, order 16.

On the regular octagon, there are eleven distinct symmetries. John Conway labels full symmetry as r16.[5] The dihedral symmetries are divided depending on whether they pass through vertices (d for diagonal) or edges (p for perpendiculars) Cyclic symmetries in the middle column are labeled as g for their central gyration orders. Full symmetry of the regular form is r16 and no symmetry is labeled a1.

The most common high symmetry octagons are p8, an isogonal octagon constructed by four mirrors can alternate long and short edges, and d8, an isotoxal octagon constructed with equal edge lengths, but vertices alternating two different internal angles. These two forms are duals of each other and have half the symmetry order of the regular octagon.

The octagonal shape is used as a design element in architecture. The Dome of the Rock has a characteristic octagonal plan. The Tower of the Winds in Athens is another example of an octagonal structure. The octagonal plan has also been in church architecture such as St. George's Cathedral, Addis Ababa, Basilica of San Vitale (in Ravenna, Italia), Castel del Monte (Apulia, Italia), Florence Baptistery, Zum Friedefrsten Church (Germany) and a number of octagonal churches in Norway. The central space in the Aachen Cathedral, the Carolingian Palatine Chapel, has a regular octagonal floorplan. Uses of octagons in churches also include lesser design elements, such as the octagonal apse of Nidaros Cathedral.

Architects such as John Andrews have used octagonal floor layouts in buildings for functionally separating office areas from building services, such as in the Intelsat Headquarters of Washington or Callam Offices in Canberra.

I feel like the outback octagon was a part of our week for many of us, whether as players (like me) or as viewers. Now that it's done and fully uploaded to youtube, it might be fun to have a bit of a post game chat about the tournament.

this collection features patterns incorporating 4" octagon and 1" bouchon in neutral shades: weathered white, moroccan sea salt, charred cedar, vintage rose and natural unglazed terracotta. each octagon can be mixed with a contrasting bouchon to create countless pattern combinations and a truly custom look. the collection offers outstanding variations of color and texture, and is perfect as an accent wall or even for a floor surface. also included are pre-assembled mosaic border designs perfect to frame floors, cap backsplashes and more.

To combat this, I'll wrap a blanket around the octagon, leaving the black heating console and vent hole open. Doing this makes it possible to run the Octagon in the early hatching season when nights still get very cold, without too much dip in temperature.

A new octagon! I love this shape but it was too small for what I need so I decided to add borders. But first, I had to turn the octagon into a square. This is an easy task- you just have to add corner triangles.

The Armour-Stiner (Octagon) House is one of the most visually unique homes in the world. It is the only known fully domed octagonal residence and the only house built in the form of an ancient classical temple. The Octagon House was built in the 1860s by Paul J. Armour, a New York City financier. In this pre-Civil War period octagonal houses were a popular mode of construction following the publication of a book, The Octagon House, A Home for All, by Orson Squire Fowler, a phrenologist, sexologist and amateur architect. In 1872, the house was purchased by Joseph Stiner, a prominent New York City tea merchant. His alterations created the present unique structure. With plans to use the house as a summer retreat, Stiner added the dome and the verandah to create a classical, elaborately detailed Roman temple.

Created as a summer retreat by tea-importer Joseph Stiner, its shape was based on the theories of Orson Squire Fowler, a phrenologist, who believed octagonal houses enclosed more space, allowed the sun in at all times, and permitted more views into the landscape. This one hour tour introduces you to the history of the house and its occupants as well as the landscape of the property.

"It was just the name of it," Cusson said. "I don't even remember if there was an actual octagon in the movie." (There were two: a building Norris fights his way through during the climax and a small, sand-covered area surrounded by wooden posts to contain sparring matches.) "I had no martial arts background. The reason there's an Octagon is because of Chuck Norris."

Harrison showed Pillot his sketches, and Pillot picked out the octagon-shaped cage. Or, to hear Pillot tell it, he was the one to suggest the shape. "I said, 'We need an octagon,'" Pillot recalled. "That happened in a meeting with Rorion and Art. I felt like you should go from four sides, like in boxing, to eight."

Davie has no recollection of this conversation. Pillot, Harrison said, "didn't come up with the idea of an eight-sided octagon-shaped fighting surface and didn't provide any input to my Octagon design or any of my other UFC designs. He never provided any input to any of my set designs. He was a producer."

Harrison is equally adamant that Cusson had no voice during the design process. "I do my design work independently," he said. But Cusson insists he broached the subject of an octagon with an overworked Harrison, who was tackling multiple projects at the time.

"We were working together," Cusson said. "He told me he was busy, so we brainstormed. I said, 'How about an octagon? There was this martial arts movie ...' It was that easy. Greg was the point man on the project, but the actual design of the thing came from me."

However the eight-sided design had been struck, it met SEG's approval. Harrison went through a few iterations with Pillot -- an octagonal surface surrounded by a cage and ropes and another with a raised platform. Flexible netting gave way to fencing; a surface 40 feet in diameter gave way to 30.

"The reason was so no one could get pinned in a corner," said Patschull, who often goes by the nickname "Kazja." "That's why I went with an octagon. My investors said, why not use a boxing ring? I said no, a person would fall out or hurt someone in the audience. That's the reason I went with the fencing."

"Their first flyer went out, and it said they were going to do it in a wooden pit," said Patschull, referring to the Milius plug in the UFC's early advertising. "Then all of a sudden they're using an octagon. They're going to try and claim they created it. They saw my show."

Davie's presence convinced Patschull that SEG had co-opted his design. For much of the 1990s, he would use octagon-shaped cages and mats in regional events while flaunting his self-styled "Octagon Originator" label in magazine ads. Later ventures like Octagon Nation, a line of apparel, would net him cease-and-desist letters from current UFC owner Zuffa, though he has yet to be dragged into litigation. He remains adamant that he should be credited with the cage design and often circulates his disdain for the legal notices online.

SEG, meanwhile, received a trademark in September 1997 for an "octagon-shaped fighting surface," a protection that Zuffa inherited. "They filed for trademark incontestability as well," added Twilley, which he said insulates against virtually all challenges against ownership of the mark.

The Feusier Octagon House, one of the oldest houses on Russian Hill, is visible in early photographs of the hill, near the summit, not closely surrounded by other buildings. It is one of only two surviving octagonal houses in the San Francisco Bay Area. The other is the Colonial Dames Octagon on Gough Street. (The extant Marine Exchange Point Lobos Lookout Station was built in 1927 with an octagonal footprint.)Octagon houses were a national fad from 1850 until 1870 as the result of a book by Orson Squire Fowler, A Home for All; or, the Gravel Hall and the Octagon Mode of Building.Fowler, a New York phrenologist who identified one's well-being with the shape and construction of his domicile, proposed a new and cheap way to construct houses for the new age.The octagon form was prescribed so that every room could receive sunlight at some time of the day.A hundred or more octagons houses survive in the United States. At one time there were at least five in San Francisco, as well as others in the Fruitvale section of Oakland and elsewhere in the Bay Area.Of the San Francisco Octagons, all but one were on or near Russian Hill, the sole exception being Cyrus Palmer's home on Rincon Hill. It is likely that all of these were built by a single builder from the eastern United States.Louis Feusier first appears as the owner and occupant in 1875. Feusier is said to have been a companion of such San Francisco notables as Leland Stanford and Mark Twain. His business interests included wholesale produce, mining, salmon canning, winemaking and the importation of oriental goods. The Feusiers added a third story with Mansard roof surmounted by an octagonal cupola. Like other buildings on Russian Hill, the house escaped the 1906 Earthquake but was menaced by the Fire. The outbuildings were dynamited but the main house was saved. Feusier's wife Louise lived here until her death, as did their son Clarence who died in 1951. In 1954 the Feusier Octagon was sold by the family. 006ab0faaa
