@Nikolaos
[5 5 5] can make a triangle, but not a *right* triangle (with one 90-degree angle). See the Wikipedia page definition.

FYI, "right triangle" is American English, "right-angled triangle" (or "right-angle triangle") is British English. Neither expression reflects the 'power' of the language.
