... In year 1870 W.K.Clifford published a paper (see [CLI]) showing that for each positive integer n > 3 there will be associated a point for each even n and a circle for each odd n which reduces to the known Miquel point and the Miquel circle in the cases n = 4, n = 5. Moreover, for each odd n ≥ 5 the ...

... Also the quadrilateral ABP C is cyclic (because P has been chosen on the circumcircle of ABC). We deduce that ∠BP C + ∠BAC = π ⇒ ∠BP C = π − ∠BAC. So ∠U P W = ∠BP C, as desired. In conclusion, we have proved that ∠BV U = ∠CV W . This implies that the points U, V , and W are collinear. 2*. As the hin ...

History of geometry
Geometry (from the Ancient Greek: γεωμετρία; geo- ""earth"", -metron ""measurement"") arose as the field of knowledge dealing with spatial relationships. Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers (arithmetic).Classic geometry was focused in compass and straightedge constructions. Geometry was revolutionized by Euclid, who introduced mathematical rigor and the axiomatic method still in use today. His book, The Elements is widely considered the most influential textbook of all time, and was known to all educated people in the West until the middle of the 20th century.In modern times, geometric concepts have been generalized to a high level of abstraction and complexity, and have been subjected to the methods of calculus and abstract algebra, so that many modern branches of the field are barely recognizable as the descendants of early geometry.
