The geometrical structure depicted in the picture is called;Spiral of Theodorus. In geometry, the spiral of Theodorus is a spiral composed of contiguous right triangles. It was first constructed by Theodorus of Cyrene.The principle of construction is based on the Pythagorean theorem.Created by: Tschuka hard 46% Hippocrates hairpinHippocrates hairpin29Spiral of ArchimedesSpiral of Archimedes102Euclid's crustEuclid's crust52Spiral of TheodorusSpiral of Theodorus161geometry riddles » In which year did Leonhard Euler introduced the symbol "i" to represent the square root of -1 ?In 1777. The letter "i" as a designation of the element from -1 was proposed by Leonhard Euler in 1777. Later, from 1801, this designation was popularized by Carl Friedrich Gauss. Currently, it is the most commonly used symbol of the imaginary unit.Created by: Tschuka hard 40% in 1555in 1555152in 1666in 1666473in 1777in 1777748in 1888in 1888487numbers riddles » The illustration shows the figure known in mathematics as;Lune of Hippocrates,. In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically.Created by: Tschuka very hard 22% Tales' sailsTales' sails40Pythagorean sicklesPythagorean sickles40Archimedes' archesArchimedes' arches41lune of Hippocrates,lune of Hippocrates,36geometry riddles » Which mathematician is it?Henri Poincaré. Jules Henri Poincaré was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as " The Last Universalist"n since he excelled in all fields of the discipline as it existed during his lifetime. He was responsible for formulating the Poincaré conjecture, which was one of the most famous unsolved problems in mathematics until it was solved in 2002–2003 by Grigori Perelman. In his research on the three-body problem.Created by: Tschuka very hard 23% Grigory PerelmanGrigory Perelman37Gottfried Wilhelm LeibnizGottfried Wilhelm Leibniz141Henri PoincaréHenri Poincaré100Stefan BanachStefan Banach143scientists riddles » Which number is the largest?100 quadrillion .
