Russian Forms/Inflections:

"Периметр" is a masculine noun (мужской род) borrowed from Greek via English, and it follows the standard third-declension pattern for inanimate nouns in Russian. It has regular inflections based on case and number. Below is a table of its declensions in the singular form (plural is less common but follows similar patterns).

Note: The word is invariant in plural forms in most contexts, but if used, it becomes "периметры" in nominative plural. There are no irregular changes.

Russian Synonyms/Antonyms:

• Synonyms:
  • окружность (okružnostʹ) - Specifically for circles; implies a curved boundary, with a subtle difference in shape context.
  • край (kraj) - Informal synonym in non-technical contexts, meaning "edge" or "border," but less precise for mathematical use.
• Antonyms:
  • площадь (ploschadʹ) - Refers to "area" inside the shape, contrasting with the external boundary.

Related Phrases:

• Расчёт периметра (raschot perimetra) - Calculation of the perimeter; used in mathematical problem-solving.
• Периметр территории (perimetr territorii) - Perimeter of the territory; common in security or land management contexts.
• Измерение периметра (izmereniye perimetra) - Measurement of the perimeter; applied in engineering or construction.

Usage Notes:

"Периметр" directly corresponds to the English "perimeter" in technical and mathematical contexts, making it a straightforward borrowing. It is primarily used in formal or educational settings, so avoid it in casual conversations. When choosing between translations, "периметр" is the most accurate for geometric contexts, while "окружность" should be reserved for circular shapes. Grammatically, always treat it as a masculine singular noun and adjust for case as needed in sentences. For example, in prepositional phrases, use the prepositional case (e.g., "на периметре" for "on the perimeter").

Common Errors:

• Confusing "периметр" with "площадь": English learners often mix up perimeter (boundary) with area (internal space). Incorrect: "Площадь круга — 2πr" (wrongly using "площадь" for perimeter). Correct: "Периметр круга — 2πr". Explanation: "Площадь" means area, so use "периметр" for outer measurements to avoid conceptual errors.

• Improper inflection: Forgetting to change the case, e.g., saying "of периметр" instead of "of периметра". Incorrect: "Расчёт of периметр" (non-standard). Correct: "Расчёт периметра". Explanation: Always inflect based on the sentence structure to maintain grammatical accuracy in Russian.

Cultural Notes:

"Периметр" is a term heavily influenced by Western scientific traditions, particularly from Greek mathematics, and does not carry significant cultural connotations in Russian everyday life. However, in Russian educational systems, it is emphasized in STEM curricula, reflecting Russia's strong historical focus on mathematics and engineering, as seen in figures like Euler and Lobachevsky.
