how is [5 5 5] false?

the cyclist on 16 Nov 2017

@Nikolaos

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

right triangle>a triangle with one 90 degree_angle?from this point,we can see the expression power of English sucks when compared to that of chinese

David Verrelli on 3 Nov 2017

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