The Douglas Triangle, Khufu and Khafre

descriptionPublicationkeyboard_double_arrow_right Report 30 Dec 2021 English Zenodo
Authors: Douglas, Ian;

The Douglas Triangle, Khufu and Khafre

Abstract

The Douglas triangle is a special right triangle using �� and ���3. It appears that its proportions and peculiarities impressed the Giza planners so much that they used it, when scaled by 50��, for the base lengths of the Khufu and Khafre pyramids. This paper presents the triangle and discusses some of its interesting features.

1.1.0 2 January 2022 : Added site diagrams with P5 cross having Douglas triangle and �� ratios.

Keywords

Giza, geometry, history of mathematics, Egyptology, archaeogeometry, golden ratio
