There exist in the hyperbolic plane ( countably) infinitely many pairs of constructible circles and constructible regular quadrilaterals of equal area, which, however, are constructed simultaneously. The hyperbolic plane does not contain squares (quadrilaterals with four right angles and four equal sides), but instead it contains regular quadrilaterals, shapes with four equal sides and four equal angles sharper than right angles. Although the circle cannot be squared in Euclidean space, it sometimes can be in hyperbolic geometry under suitable interpretations of the terms. The Archimedean spiral can be used for another similar construction. And if you remember that Alchemy is sometimes referred to as a micro. For example, Dinostratus' theorem uses the quadratrix of Hippias to square the circle, meaning that if this curve is somehow already given, then a square and circle of equal areas can be constructed from it. In this woodcut from Tetragonismus idest circuli quadratura we will see how the. The task is to construct from a given circuit in a finite number of steps, a square with the same area. īending the rules by introducing a supplemental tool, allowing an infinite number of compass-and-straightedge operations or by performing the operations in certain non-Euclidean geometries makes squaring the circle possible in some sense. Squaring the circle is a classic problem of geometry. In 1882, the task was proven to be impossible, as a consequence of the Lindemann–Weierstrass theorem, which proves that pi ( π is transcendental and therefore that squaring the circle is impossible. The difficulty of the problem raised the question of whether specified axioms of Euclidean geometry concerning the existence of lines and circles implied the existence of such a square. It is the challenge of constructing a square with the area of a circle by using only a finite number of steps with a compass and straightedge. Squaring the circle is a problem in geometry first proposed in Greek mathematics.
