Russian Translation(s) & Details for 'polygon'

English Word: polygon

Key Russian Translations:

• многоугольник [mnɐgəʊˈɡɔlnʲɪk] - [Formal, Mathematical term]

Frequency: Medium (Common in technical and educational contexts, but not in everyday conversation)

Difficulty: B2 (Intermediate; requires familiarity with mathematical vocabulary and basic Russian noun declensions)

Pronunciation (Russian):

многоугольник: [mnɐgəʊˈɡɔlnʲɪk]

Note on многоугольник: The stress falls on the third syllable ("gólnʲɪk"), which can be tricky for learners due to the consonant cluster. Pronounce the "г" as a voiced velar fricative.

• Правильный многоугольник, такой как квадрат, является подтипом этой фигуры.

  A regular polygon, such as a square, is a subtype of this figure.

Russian Forms/Inflections:

"Многоугольник" is a masculine noun in the second declension. It follows regular noun declension patterns in Russian, with changes based on case and number. Below is a table of its inflections:

Note: The word is invariant in terms of gender but changes predictably with case and number, as shown above.

Russian Synonyms/Antonyms:

• Synonyms: полигон (more general, often used in contexts like land surveying or computing, but less precise for geometric shapes)
• Antonyms: круг (circle) - Refers to a curved shape, contrasting with the straight-sided nature of a polygon.

Related Phrases:

• Правильный многоугольник - A regular polygon; refers to a polygon with equal sides and angles, commonly used in geometric discussions.
• Неправильный многоугольник - An irregular polygon; used to describe polygons without equal sides or angles, often in advanced math contexts.
• Составной многоугольник - A composite polygon; indicates a polygon made up of multiple simpler shapes, relevant in design and architecture.

Usage Notes:

"Многоугольник" directly corresponds to the English "polygon" in mathematical contexts, but it's primarily used in formal or educational settings. Be mindful of its declension based on Russian grammatical cases; for example, use the genitive form "многоугольника" after prepositions like "of" (e.g., "стороны многоугольника" for "sides of the polygon"). If you're translating from English, choose this term for precise geometric discussions rather than everyday language. In informal speech, Russians might simplify explanations without this word.

• Grammar tip: As a masculine noun, it agrees with adjectives and verbs in gender.
• Context guidance: Prefer "многоугольник" in scientific writing; for computing, "полигон" might be more appropriate due to overlap with English "polygon" in graphics.

Common Errors:

One common mistake is confusing "многоугольник" with "полигон," which can mean a fenced area or a polygon in computing/graphics contexts. For example:

• Incorrect: Использовать полигон для описания геометрической фигуры в уроке (This incorrectly uses "полигон" for a geometric shape, which might imply a land plot).
• Correct: Использовать многоугольник для описания геометрической фигуры в уроке (This properly uses "многоугольник" for the geometric context).
• Explanation: Learners often borrow from English without checking nuances, leading to semantic errors. Always verify the context to avoid this.

Cultural Notes:

While "многоугольник" is a neutral mathematical term without strong cultural connotations, it reflects Russia's emphasis on STEM education, influenced by historical figures like Lobachevsky in geometry. In Russian culture, such terms are integral to academic discourse, highlighting the importance of precise language in sciences.
