Hello everyone,

I'd like to know what you call a set square in Russian - in our textbooks and dictionaries I found three various names: угольник, наугольник and even треугольник. Which of them is correct?

    All of them really mean "set square", however contemporary and mostly used term is угольник.
    Наугольник is obsolete term; треугольник is rather colloquial term and probably mostly encountered in school speech.
