The Egyptians used ropes with knots to ensure right angles and perfect square bases. They used that on method of geometry to build big pyramids

Heron's formula

jacobrubins — 2024-11-06 17:30:38 UTC

Area = Square root of√s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + c)/2. This formula is used to calculate the area of triangles, given the three sides of the triangle.

an ancient Egyptian document dating back to around 1850 BCE that contains mathematical problems and their solutions. Showcasing early algebraic and geometric techniques.

Golden ratio

jacobrubins — 2024-11-08 16:40:43 UTC

The golden ratio was known in 300 B.C., when Euclid described the method of geometric construction. It has been argued that the golden ratio was used in the design of the Parthenon and other ancient Greek buildings, as well as sculptures, paintings, and vases.

Thales of miletus

jacobrubins — 2024-11-12 13:50:05 UTC

He was known for introducing the theoretical and practical use of geometry to Greece, and has been described as the first person in the western world to apply deductive reasoning to geometry,

Pythagoras

jacobrubins — 2024-11-12 13:52:05 UTC

a cornerstone of math that helps us find the missing side length of a right triangle. This method was used in the 570 BC- 495 BC

Zeno's paradox

jacobrubins — 2024-11-12 13:54:13 UTC

for motion to occur, an object must change the position which it occupies. Zeno's paradoxes were thus solved from the 17th century onward

The earliest evidence of volume calculation came from ancient Egypt and Mesopotamia as mathematical problems. Approximating volume of simple shapes such as cuboids, cylinders, frustum and cones.

Euclid

jacobrubins — 2024-11-12 14:04:29 UTC

euclidean geometry is the study of Geometry based on the undefined terms such as points, lines, and planes of flat spaces. In other words, it is the study of geometrical shapes both plane shapes and solid shapes and the relationship between these shapes in terms of lines, points, and surfaces.
