Adjacent angles are one of the earliest and most important concepts to learn in basic geometry, as they have applications in further subjects like trigonometry, physics, and engineering. Effective ...

The Trisection of the Angle by Plane Geometry: Verified by Trigonometry with Concrete Examples. By Dr. J. Whiteford. Pp. 169.

In this paper we investigate angle geometry in the universal Teichmüller space. We construct three examples of triangles bounded by geodesic segments such that the first example has the sum of the ...

A scientist has revealed that an ancient clay tablet could be the oldest and most complete example of applied geometry. The surveyor's field plan from the Old Babylon period shows that ...

Si.427 is the oldest known example of applied geometry, and researchers say it was compiled by a Babylonian land surveyor. Si.427 dates from the Old Babylonian (OB) period from 1900 to 1600 BCE.

The oldest example of applied geometry has been discovered on a 3,700-year-old clay tablet featuring maths attributed to Pythagoras 1,000 years later.
