describe what a glide reflection or screw motion is, has no discussion of differential geometry, only mentions 'analytic geometry' per se in a throwaway aside, barely mentions other coordinate systems (and what little it does is inaccessibly jargony/abstract), makes no mention of the geometry of oriented planes, etc. etc. The fundamental notions that make a "Euclidean space" are lines (and higher-dimensional flat subspaces), parallelism, angles and perpendicularity, and distance and spheres. Just as planar Euclidean geometry substantially focuses on lines and line segments, angles, triangles and circles (and then also conics, algebraic curves, ...), higher-dimensional Euclidean geometry substantially focuses on those same planar objects and higher-dimensional analogs like tetrahedrons, spheres, and quadrics.

For instance, this article currently makes no mention of 144: 175: 829:, then proceeding to discuss axiom systems, a (currently very incomplete and somewhat idiosyncratic) historical summary, an idiosyncratic smattering of sentences and pictures about applications, and concrete details mainly provided as examples rather than as the primary topic. It would also be great to dramatically improve the article 379:}; that is, it identifies clearly and unambiguously the subject of the article in a way that is understandable to everybody. The same applies to the short description, which is aimed to help to recognize the searched article in the result of a search query. This aim is clearly and perfectly fulfilled by the present short description. 785:
generally coming here because they want to find out the formal/technical details and logical ordering of the basic definition(s) Marcel Berger chose to use in his (very fine) textbook, which was convenient for his particular purposes of setting up a framework for the rest of the book, in a logically

Having both a singular and a plural form would be very confusing to most readers. The ambiguity between “the Euclidean space” (which is three dimensional) and “a Euclidean space” (which can have any dimension), is not an artefact of Knowledge, but relies on the common use. So, it cannot be resolved

It’s fine to make a separate article (which can even be significantly expanded). However, all of the material currently on this page is easily in scope (indeed, the material on this page should be further expanded here), and removing it and replacing with a useless 'excerpt' is a major regression.
991:
There should be an article at 'Euclidean space', it should focus on Euclidean space per se as its primary topic (but also including discussion of the relationship to non-Euclidean, pseudo-Euclidean, affine, projective, etc. spaces), and it should encompass both the basic geometry and more abstract
697:
The same is to some extent true of this article in general. As many concepts/sections as possible should be pitched to be legible to e.g. high school students or laypeople. It should include more specific details about concrete geometrical figures (or at least obvious links to other articles where

The standard way to mathematically define a Euclidean space, as carried out in the remainder of this article, is as a set of points on which a real vector space acts, the space of translations which is equipped with an inner product. The action of translations makes the space an affine space, and
701:
It’s wild to me that this article does not discuss the concepts of spheres or conics/quadrics (or any other curves or surfaces) or simplexes (or any other polyhedra), only mentions the word "triangle" in the context of the triangle inequality and does not mention the word "trigonometry", does not

Today, a well-meaning editor added a one-sentence paragraph to the lede, stating that Euclidean space is a metric space. That's true, but it's just one of many such statements that could be added. I propose that the paragraph be either deleted or expanded --- perhaps to something like, "Euclidean

This article is about the current mathematical concept of Euclidean space. There is essentially one example per natural number. The evidence suggests that the example corresponding to the natural number 2 is at least as old as the example corresponding to the natural number 3.

1395:. Moreover, I do not agree that "the" Euclidean space is the three-dimensional one. That is contrary to my sense of the math literature, where the word "space" does not imply three dimensions. The sentence, that Fgnievinski is citing from this article, should be changed. 335:
The lead reluctantly gives out a definition only in the last paragraph. Definitions should appear in the opening sentence. The short description is equally vage: "Fundamental space of geometry". Can we anticipate some sort of definition, e.g., "Euclidean space is a

Most of the time there's no problem figuring out from context which among Euclidean 3-space vs. any Euclidean space is intended. When there is some ambiguity authors can just explicitly say "Euclidean 3-space" or "any Euclidean space" or whatever.

and a couple of other editors broke the equilibrium and essentially re-wrote it (mostly for the better, in my opinion). My point is that the current text is, in a sense, new/immature and ripe for continued polishing/expansion.

The renaming was necessary to make more explicit the scope of the present article. It is not specifically about the ordinary three-dimensional Euclidean space, it's about the general case of Euclidean spaces of any dimension.
1370:. Most people -- including scientists, engineers, etc. (mathematicians excepted) -- would equate "Euclidean space" with 3D, not n-dimensional spaces. (I'd like to thank for the arguments, pro or con, and note this is not a 398:

The lede currently says that three-dimensional Euclidean space was the first example. The nearest citation does not support this claim. I suspect (without citation) that two-dimensional Euclidean space was the first

That section doesn't define a unique "Euclidean distance formula", but instead gives several examples of formulae, all of which calculate Euclidean distance in different situations or given different information.

This is mostly incoherent to someone without significant math background; we are more or less assuming someone has studied 2+ years of undergraduate level pure math courses before trying to approach this

That's a crucial point: should the article title reflect the usage in modern mathematical literature or the broader literature in physics, science, engineering, etc.? How about a less verbose version: "

Even if we accepted the current structure this article is very hard for non-expert readers. For example the concepts of "inner product" and "affine space" are first mentioned as:
