Then what is the basis of the heiroglyph alleged to mean pyramid??

Rhind or Moscow?? Which english translation.??

I know about triangles. They're not that difficult.

A cubit is a unit of linear distance measure, it can be converted into any other unit of linear distance measure.
Which drawing illustrates an object of 220 cubits high and 330 cubits at the base?

Triangles.. The Greeks were fascinated by them.. Triangles are fun.. and necessary for all kinds of stuff..
Like surveying land. Which is also pretty big and rely's totally on triangulation.

Triangles and Trapezoids, which are usually two triangles.

You need 'Triangles for Dummies' to do the frustum.
Which isn't a pyramid.
> Pretentious Goose!
It's a trigonometry/geometry textbook with no mention of a true pyramid or any claim to be about pyramids.
Just triangles and cylinders.
It's one hell of a stretch too claim it's a handbook on pyramid construction.
The computation of cylinders is really relevant to pyramid construction?
What is the glyph for 'Triangle'??
So we have a drawing of an acute isosceles triangle, accompanied by notation, which somehow through an enormous leap of faith transmogrify's into a pyramid.??
How did that happen??
It's like me claiming that a basic trigonometry textbook is all about, and exclusively about tower cranes.. Simply because tower cranes consist of lots of triangles glued together.
How about it may just be a trig text book??
A book about triangles. "Triangles for Dummies".
Get a stick and a piece of string, knot the ends of the string to the stick so's they slide on the stick. Make a triangular loop in the string with your finger. You've got a triangle .. Now slide your finger along the string keeping the triangle taught. You can even vary the distance between the knots.
You can now compute any triangle you like.
'String and stick' trigonometry. Which is pretty cool until the Greeks come along and make things appear more difficult.
(although way more accurate). Especially for surveying.
Could the glyph mean 'surveyed land' .. Measuring Stick and Triangle... ??
Linear measurement and triangulation. Which is a survey. Is it not?
Christ it's even similar to this, which is also all about measuring and surveying.
Probably unrelated, but similar in that they are both good examples of good graphic design, the meaning derived through purpose and simplification.
