Geometry

First Egyptian Pyramid constructed, requiring knowledge of how to build pyramids with square bases out of blocks of stone.

The Moscow Papyrus is written containing 25 examples of Egyptian math.

a^{2} + b^{2} = c^{2}

way to figure out the legs or the hypotenuse

Found out that circle is 360 degrees

Hipparchus' thoughts and teachings of Trigonometry

It was developed over the years by Pythagoras and the Pythagoreans, Plato, Aristole, Euclid, and others

Euclid complies, organizes and systematizes geometric ideas which had been discovered and proven into thirteen books, called ELEMENTS (, a book discussing Euclidean geometry. The Elements is a collection of 13 books of definitions, postulates, and axioms. It became the 3rd most popular book in the world, after the Koran and the Bible.)

Eratosthenes determines that the Earth is spherical and computes its diameter

Appolonius works on Conic Sections

Archimedes (287 BC - 212 BC) does work on circles, spheres, areas, infinite series, and other things

Brahmagupta created a formula for finding the area of a quadrilateral, with sides a,b,c,d, enclosed by a circle: A = The Sq. Root of (s-a)(s-b)(s-c)(s-d). S is the semiperimeter, is found by the formula s=(a+b+c+d)/2

Medieval Muslims synthesized algebra and geometry by placing points on a coordinate plane.

The "Mathematical" pope

geometry, optics, etc

Trigonometry

Gauss developed the Gauss method for adding large amounts of consecutive numbers when he was six. However, his most important creation is that of non-Euclidean geometry. Non-Euclidean geometry is geometry not based on the postulates of Euclid. This includes times when the parallel postulate isn’t true. Parallel Postulate – Through a given point not on a line, there is one and only one line parallel to it.
