The question involves work on geometry and it may be necessary to use some angle facts. In this diagram there is a triangle and a straight line. Although the angle looks obtuse , it might not be.

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 ...

The question involves work on geometry and it may be necessary to use some angle facts. In this diagram there is a triangle and a straight line. Although the angle looks obtuse , it might not be.

Researchers in Australia have made a discovery that may shake up the history of mathematics, revealing evidence of applied geometry being used for the purposes of land surveying some 3,700 years ...

Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, ...

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.
