7.2.4 Geometry of more than 3 dimensions. 7.3 The 20th ... This assumes that π is 4×(8/9) 2 (or 3.160493 ... the Mo Jing stated that a point is the smallest unit, ...
A regular n-gon has a solid construction if and only if n=2 a 3 b m where a and b are some non-negative integers and m is a product of zero or more distinct Pierpont primes (primes of the form 2 r 3 s +1). Therefore, regular n-gon admits a solid, but not planar, construction if and only if n is in the sequence
The Koch snowflake, with fractal dimension=log4/log3 and topological dimension=1. Traditional geometry allowed dimensions 1 (a line or curve), 2 (a plane or surface), and 3 (our ambient world conceived of as three-dimensional space). Furthermore, mathematicians and physicists have used higher dimensions for nearly two centuries. [71]
Absolute geometry is a geometry based on an axiom system consisting of all the axioms giving Euclidean geometry except for the parallel postulate or any of its alternatives. [69] The term was introduced by János Bolyai in 1832. [70] It is sometimes referred to as neutral geometry, [71] as it is neutral with respect to the parallel postulate.
Euclidean Geometry is constructive. Postulates 1, 2, 3, and 5 assert the existence and uniqueness of certain geometric figures, and these assertions are of a constructive nature: that is, we are not only told that certain things exist, but are also given methods for creating them with no more than a compass and an unmarked straightedge.

260 BC – Archimedes proved that the value of π lies between 3 + 1/7 (approx. 3.1429) and 3 + 10/71 (approx. 3.1408), that the area of a circle was equal to π multiplied by the square of the radius of the circle and that the area enclosed by a parabola and a straight line is 4/3 multiplied by the area of a triangle with equal base and height ...
The Sijil Pelajaran Malaysia (SPM), or the Malaysian Certificate of Education, is a national examination sat for by all Form 5 secondary school students in Malaysia.It is the equivalent of the General Certificate of Secondary Education (GCSE) of England, Wales and Northern Ireland; the Nationals 4/5 of Scotland; and the GCE Ordinary Level (O Level) of the Commonwealth of Nations.
[1] From the time of Plato through the Middle Ages, the quadrivium (plural: quadrivia [2]) was a grouping of four subjects or arts—arithmetic, geometry, music, and astronomy—that formed a second curricular stage following preparatory work in the trivium, consisting of grammar, logic, and rhetoric.
