If the apex of the pyramid is directly above the center of the square, it is a right square pyramid with four isosceles triangles; otherwise, it is an oblique square pyramid. When all of the pyramid's edges are equal in length, its triangles are all equilateral. It is called an equilateral square pyramid, an example of a Johnson solid.
The problem also demonstrates that the Egyptians were familiar with square roots. They even had a special hieroglyph for finding a square root. It looks like a corner and appears in the fifth line of the problem. Scholars suspect that they had tables giving the square roots of some often used numbers. No such tables have been found however.

The type of pyramids can be derived in many ways. The base regularity of a pyramid's base may be classified based on the type of polygon: one example is the star pyramid in which its base is the regular star polygon. [24] The truncated pyramid is a pyramid cut off by a plane; if the truncation plane is parallel to the base of a pyramid, it is ...
Which civilization was known for the Great Pyramid of Giza? ... Right Angle. How many sides are there in an octagon? ... What is the square root of 36? Answer: 6. How many feet are in one mile ...
Casing stone from the Great Pyramid. The seked of a pyramid is described by Richard Gillings in his book 'Mathematics in the Time of the Pharaohs' as follows: . The seked of a right pyramid is the inclination of any one of the four triangular faces to the horizontal plane of its base, and is measured as so many horizontal units per one vertical unit rise.
The change of the angle have been made as a stability precaution in reaction to a catastrophic collapse of the Meidum pyramid while it was still under construction. 29°47′25″N 31°12′33″E / 29.79028°N 31.20917°E / 29.79028; 31
The construction of the Egyptian pyramids can be explained with well-established scientific facts, however there are some aspects that are even today considered controversial hypotheses. The construction techniques used seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. It is believed that ...
Scholars have spent decades delving into what techniques the builders used to position the pyramid’s so they face almost absolute north, south, east & west. Giza pyramid’s nearly perfect ...
