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)[reply]

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.

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:
