I'm not sure what's the best option to proceed here. One option might be to make (leave?) this a statement about real numbers of distance one and change the terminology accordingly. Another option might be to make make this statement about sequential integers or naturals (I suppose you intended that)
595:
I agree that current terminology is not helpful if it is understood as a statement about real numbers (and I couldn't find any book or paper using such terminology in a superficial search). The reason why I reverted this was that if restricted to natural numbers it somewhat redundant to the theorem
694:
Well allowing (positive) real numbers instead of natural numbers turns the whole thing into (trivial) geometric theorem (as stated above and the notion of bases makes sense as base side) rather than being just an geometric illustration of number theoretic theorem. Whether such a "geometric theorem"
607:
As far as "adjacent squares" in terms of real numbers are concerned, there is a way to make some sense of geometrically. That if the side length of 2 squares differ by one, then the difference in area in identical to the sum of their base sides (ignoring units). You can visualize that nicely by

article. I'm not sure what the additional benefit is in allowing for real numbers here. The concept of "adjacent" squares loses its meaning and actually any real number can be expressed as a difference of squares in infinitely many

placing the squares on top of each and we could actually include such drawing into the article. Maybe that's even what the original author had in mind, but that's pure speculation on my side now.--

the sum of the square roots. I agree that the statement that an odd number can be expressed as a difference of (consecutive perfect) squares is redundant, so that sentence could simply be deleted.
140:
262:
The geometric illustration does not point out that the two rectangles represent (a-b)b. A better account of the picture would vastly help some people understand the whole article.
575:, but why would all this be worth mentioning? Describing two real numbers as adjacent is meaningless since they are uncountable and calling the square root "base" is misleading.

is worthwhile to mention here is imho a matter of taste/editorial discretion, it certainly doesn't need to be in the article, but I see no harm in mentioning it either.--
520:

and explain the terminology in that context (or modify it). In that case however we should merge that with theorem directly after to avoided having the same proof twice.
421:
296:
There is also a formula derivable from a difference of two squares to receive the difference's value. when a is a perfect square, x^2 - a = (x - a)^2 - a(a + 2x -1)

Wiktionary doesn’t state anything about numbers other than real, Wiktionary isn’t any particular authority on algebra and, at the end, Wiktionary is no more than a

A more explicit connection between the text and illustrations could help readers of wikipedia.(After all, mathematical prodigies don't need it in the first place)

My view is that it would be more interesting to discuss how the difference of consecutive perfect squares leads to a recursive formula for calculating the

It actually makes sense to mention it both articles, here it is an example for another application of the difference of squares.--

Many students would find it helpful to be told more of the relationship between the equations and the illustration.
