Information: - A triangular number or triangle number counts the objects that can form an equilateral triangle, as in the diagram on the right. The th triangular number is the number of dots composing a triangle with dots on a side, and is equal to the sum of the natural numbers from 1 to . The sequence of triangular numbers , starting at the 0th triangular number, is - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - In geometry, an octagon (from the Greek "oktagnon", "eight angles") is an eight-sided polygon or 8-gon. - In mathematics, a polygonal number is a number represented as dots or pebbles arranged in the shape of a regular polygon. The dots are thought of as alphas (units). These are one type of 2-dimensional figurate numbers. - In planar geometry, an angle is the figure formed by two rays, called the "sides" of the angle, sharing a common endpoint, called the "vertex" of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. These are called dihedral angles. Angles formed by the intersection of two curves in a plane are defined as the angle determined by the tangent rays at the point of intersection. Similar statements hold in space, for example, the spherical angle formed by two great circles on a sphere is the dihedral angle between the planes determined by the great circles. - An octagonal number is a figurate number that represents an octagon . The octagonal number for n is given by the formula 3n2 - 2n , with n > 0 . The first few octagonal numbers are : 1 , 8 , 21 , 40 , 65 , 96 , 133 , 176 , 225 , 280 , 341 , 408 , 481 , 560 , 645 , 736 , 833 , 936 ( sequence A000567 in OEIS ) Octagonal numbers can be formed by placing triangular numbers on the four sides of a square . To put it algebraically , the n - th octagonal number is x_n = n ^ 2 + 4 \ sum -- ( k = 1 ) ^ ( n - 1 ) k = 3n ^ 2 - 2n . The octagonal number for n can also be calculated by adding the square of n to twice the ( n - 1 ) th pronic number . Octagonal numbers consistently alternate parity . Octagonal numbers are occasionally referred to as '' star numbers , '' though that term is more commonly used to refer to centered dodecagonal numbers . - The term figurate number is used by different writers for members of different sets of numbers, generalizing from triangular numbers to different shapes (polygonal numbers) and different dimensions (polyhedral numbers). The term can mean - The Multinational Aircrew Electronic Warfare Tactics Facility Polygone - POLYGON is an Electronic Warfare Tactics Range located on the border between Germany and France.

Information: - The Australian Labor Party (ALP, also Labor, was Labour before 1912) is a political party in Australia. The party has been in opposition at federal level since the 2013 election. Bill Shorten has been the party's federal parliamentary leader since 13 October 2013. The party is a federal party with branches in each state and territory. Labor is in government in the states of Victoria, Queensland, South Australia, and in the Australian Capital Territory and Northern Territory. The party competes against the Liberal/National Coalition for political office at the federal and state (and sometimes local) levels. - William Richard "Bill" Shorten (born 12 May 1967) is an Australian politician who is the current Leader of the Opposition in the Parliament of Australia, in his capacity as Leader of the Australian Labor Party, after being elected party leader at the 2013 Labor leadership ballot. Shorten led Labor at the 2016 federal election at which the Liberal/National Coalition retained majority government. - South Australia (abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories. It has a total of 1.7 million people, and its population is the most highly centralised of any state in Australia, with more than 75 percent of South Australians living in the capital, Adelaide, or its environs. Other population centres in the state are relatively small. - Cameron Robert Dick is an Australian politician and member of the Australian Labor Party . He is the Minister for Health and Minister for Ambulance Services in the Palaszczuk Ministry and a member of the Queensland Legislative Assembly , representing the seat of Woodridge . Previously he was Attorney - General , Minister for Education and Minister for Industrial Relations in the Bligh government representing the electorate of Greenslopes . - Queensland (abbreviated as QLD) is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,750,500, concentrated along the coast and particularly in the state's South East. The state is the world's sixth largest sub-national entity, with an area of 1,852,642km. The capital and largest city in the state is Brisbane, Australia's third largest city. Often referred to as the "Sunshine State", Queensland is home to 10 of Australia's 30 largest cities and is the nation's third largest economy. Tourism in the state, fuelled largely by its warm tropical climate, is a major industry.
