A possible use of the Kha's protractor

TL;DR

This paper suggests that an artifact from an Egyptian tomb, possibly a protractor, could have been used by architect Kha to measure angles, indicating advanced geometric knowledge in ancient Egypt.

Contribution

It proposes a new interpretation of an Egyptian artifact as a protractor, linking it to ancient architectural practices.

Findings

The object is consistent with a protractor's shape and size.

It could have been used for measuring angles in construction.

Supports the idea of sophisticated geometric tools in ancient Egypt.

Abstract

I have recently proposed that an object, found in an Egyptian tomb and exposed at the Egyptian Museum of Torino, could be a protractor. The tomb was that of architect Kha, supervisor at Deir El-Medina during the 18th Dynasty, and his wife Merit. Considering then the object as a protractor, the architect could have used it to measure the angle of the inclined planes.
