All prime angled triangles / what are they called?
[edit]7 years ago I found out these triangles that were made of prime numbers as its three angles. There is only six of them and they look like shards. They are made of the prime numbers 2 and several other prime numbers as angles. I wrote about them here https://blog.centroid.eu/c?article=1471335755 . My question is has anyone found these before? What are they called? 2003:D2:570D:ED00:155B:5A07:2CE3:37AE (talk) 04:48, 20 August 2023 (UTC)
- For an angle, being an integer or being a prime number depends on the choice of an angle unit. If you consider angles in degree, this amounts to decompose 178 into a sum of two primes. This is a special case of Goldbach's conjecture. As these few triangles have no other remarkable property, I doubt that they have ever got a specific name. D.Lazard (talk) 08:39, 20 August 2023 (UTC)
- The concept you discovered involving triangles with angles that are all prime numbers, specifically including 2 as one of the angles, is indeed a unique and interesting idea. However, there does not appear to be a widely recognized name for such triangles in mathematical literature. These types of triangles aren’t typically discussed in standard geometric or number theory contexts, which might explain why they are not commonly mentioned or categorized.
- The closest related concept might be “Prime Triangles,” but this usually refers to a different idea—triangles with rows containing consecutive numbers that sum to a prime number Johnsosd (talk) 15:19, 11 August 2024 (UTC)
missing subtopic: needle triangle
[edit]There is an additional type of triangle that should be dealt-with in this article: the often-used meta-term: 'needle triangle'.
Here is the link to an article ('Spherical Parameterization and Remeshing') on the web that uses the term:
https://hhoppe.com/sphereparam.pdf Kontribuanto (talk) 21:20, 13 April 2024 (UTC)
- This article defines the term without using it (the word "needle" appears only two times in the article, in the same paragraph). I have encounered another definition, as a triangle with a very small angle. These definitions are not equivalent although one implies the other in the case of plane triangles. For mentioning the term in the article, we need sources that provide an evidence that there is a commonly accepted definition. D.Lazard (talk) 10:52, 2 June 2024 (UTC)
Beware of nuts with angles
[edit]Triangles, particularly when associated with the Eye of Providence, are frequently cited in conspiracy theories. The triangle symbol is often linked to secret societies, occult practices, and global conspiracies. Here are a few examples of how triangles feature in conspiracy theories:
1. The Illuminati and the Eye of Providence
• The most famous association of the triangle in conspiracy theories is with the Illuminati, a purported secret society believed by conspiracy theorists to control world events. The Eye of Providence, an eye enclosed within a triangle, is often claimed to be the symbol of the Illuminati, representing their omnipresent surveillance and influence over global affairs. This symbol’s appearance on the U.S. one-dollar bill adds to the mystique and speculation surrounding it.
2. Freemasonry
• The triangle also features prominently in Masonic symbolism. The triangle, often referred to as the “Delta” in Freemasonry, represents the Deity and divine illumination. The use of this symbol in Masonic rituals and architecture has led to various conspiracy theories suggesting that Freemasons wield significant, covert influence over world governments and organizations.
3. Pyramids and Ancient Mysteries
• Pyramids, which are essentially three-dimensional triangles, are frequently cited in theories about ancient aliens, lost civilizations, and mystical powers. Some theorists argue that pyramids are energy sources or communication devices built by ancient civilizations with knowledge far beyond their time, possibly with extraterrestrial assistance.
4. The Trilateral Commission
• Another triangle-related conspiracy theory involves the Trilateral Commission, an organization founded in 1973 to foster cooperation among the U.S., Europe, and Japan. Conspiracy theorists claim that the three sides of the “triangle” in the organization’s name represent a triad of powerful entities seeking to establish a New World Order.
5. The Bermuda Triangle
• Although more of a mystery than a traditional conspiracy theory, the Bermuda Triangle has been the subject of numerous speculative ideas. Theories range from alien abductions to time warps, all centered around this triangular area in the Atlantic Ocean where ships and aircraft are said to have mysteriously disappeared.
6. Occult Symbolism
• Triangles are also a common motif in various occult practices and symbolism. Inverted triangles, triangles with eyes, or triangles intersected by lines are often interpreted as having mystical significance. Conspiracy theorists sometimes connect these symbols to rituals or groups believed to have secretive or malevolent agendas.
In summary, triangles have a deep-rooted presence in various conspiracy theories due to their symbolic associations with power, knowledge, and mysticism. Whether representing secret societies, ancient mysteries, or occult practices, the triangle remains a potent symbol in the world of conspiracy theories. Johnsosd (talk) 15:33, 11 August 2024 (UTC)
- Is this intended to be discussion about the Wikipedia article Triangle? Miscellaneous thoughts about triangles which are not directly relevant to the article are off topic and inappropriate here. –jacobolus (t) 20:17, 11 August 2024 (UTC)
- There seems to have been one or more puzzles included in the recently released Book of Bill (a novel related to the children's TV show Gravity Falls) whose answer(s) involved "triangle" and/or "eye of providence". This has caused a large number of Gravity Falls fans to come leave cryptic graffiti here in the past couple days. Please don't do that: it's not the purpose of Wikipedia talk pages. –jacobolus (t) 20:50, 11 August 2024 (UTC)
- Thank you for the clarification, Jacobolus. My intention was to contribute to the discussion by exploring an unusual geometric concept involving triangles with prime-numbered angles. I noted the recent influx of graffiti and appreciate the clarification on what might have motivated those posts. I now understand that my post may have veered off-topic for the specific focus of this Wikipedia talk page. I’ll be more mindful of the relevance of my contributions in the future. I appreciate your guidance.
- This response maintains a respectful tone while acknowledging both your original intent and the context provided by the other user’s comment. Johnsosd (talk) 03:07, 12 August 2024 (UTC)
- To be clear, my "please don't do that" is directed at people leaving graffiti, which I don't think you were trying to do @Johnsosd.
- I think the general theme of your comment could be turned to productive end, but comments here should be targeted toward improving the article Triangle rather than just talking about triangles. See WP:NOTFORUM and WP:TALK#USE. So for example, it might be reasonable to propose adding some section to the article about symbolic or mystical uses of triangles, or creating a new article focused on that topic. A section here would need to be reasonably concise, neutral, and well sourced. –jacobolus (t) 03:19, 12 August 2024 (UTC)
Hatnotes
[edit]Four different Unicode characters turn out to be redirects to this page: 🔽, 🔼, 🔺, and 🔻. The total monthly view count for all of these is less than 100. Accordingly, spending hatnote space on them seems like a waste of screen real estate. Redirects are supposed to help with searches, and hatnotes are supposed to help people confused by their searches taking them to the wrong place, but going by the next-to-nothing view counts, nobody is actually getting confused here.
I am also not convinced that "triagonal" is a sufficiently common synonym for space diagonal that it needs to be listed here. It seems to be a niche-within-a-niche term, used by a very small number of recreational mathematics people. The disambiguation notice looks like the only hatnote worth keeping. XOR'easter (talk) 22:41, 1 September 2024 (UTC)
- I can't find any examples of "triagonal" meaning diagonal of a polyhedron. I'd dump the hatnote. –jacobolus (t) 00:45, 2 September 2024 (UTC)
- As for unicode symbols: these probably should redirect to a page listing the relevant unicode block rather than here to triangle. In general having 🔓 redirect to Lock and key, 👣 redirect to Footprint, 👵 redirect to Old age, 🍕 redirect to Pizza, etc. seems like a misuse of the redirect feature, and likely to be generally unhelpful to readers. It would be better if these all redirected to some page about unicode symbols, japanese telephone emojis, or the like, with links to topics relevant to each picture listed in a table there. –jacobolus (t) 00:50, 2 September 2024 (UTC)
Top 25 report
[edit]This article has been viewed enough times in a single week to appear in the Top 25 Report. The week in which this happened: |
I'm putting this banner in an ordinary comment. I don't think there's much benefit to putting it at the top of the page and preventing it from being archived. Summary: in the past month Triangle and Eye of providence got about 1.5 million extra views each, weighted toward the first few days, based on their association with a website related to a new Gravity Falls book. During that time this talk page was vandalized a couple dozen times by Gravity Falls fans leaving graffiti, leading to temporary extra editing protection. –jacobolus (t) 03:19, 6 September 2024 (UTC)
