Meaning and Usage

"Antiparallel rays" refers to two rays that extend in opposite directions but are parallel to each other. In geometric terms, rays are defined as part of a line that has a fixed starting point and extends infinitely in one direction. When two rays are antiparallel, they are not intersecting and maintain a consistent distance apart while heading toward opposite sides of a given geometric figure.

This term is primarily used within the context of geometry and mathematics. Its frequency of use is moderate, primarily in academic discussions or textbooks concerning geometry rather than casual conversation.

Example Sentences

1. The two antiparallel rays formed a critical angle in the geometric figure.

2. Две антипараллельные лучи образовали критический угол в геометрической фигуре.

4. При изучении отражения света антипараллельные лучи могут проиллюстрировать, как работают углы в оптике.

5. The mathematician drew antiparallel rays to demonstrate the concept of parallelism in geometry.

6. Математик нарисовал антипараллельные лучи, чтобы продемонстрировать концепцию параллелизма в геометрии.

Etymology

The term "antiparallel" is derived from the prefix "anti-", meaning "opposite" or "against," and the word "parallel," which comes from the Greek "parallelos," meaning "beside one another." The term "rays" comes from the Latin "radius," meaning "spoke of a wheel" or "beam of light."

Synonyms and Antonyms

Synonyms: Opposite rays, counter-parallel rays
