reflection Explanation: Geradespiegelung is another word for Achsenspiegelung. A distinguishing description could be "reflection about a straight line," but this is unnatural and doesn't seem appropriate for a textbook glossary. https://www.studimup.de/abitur/geometrie/spiegelung/ Bei der Achsenspiegelung wird eine Figur an einer Achse bzw. Geraden, gespiegelt. Diese Gerade wird dann Spiegelachse genannt... Die Punktspiegelung ist der Achsenspiegelung ähnlich, nur dass anstatt an einer Geraden, an einem Punkt gespiegelt wird. -------------------------------------------------- Note added at 18 hrs (2018-02-09 09:18:54 GMT) -------------------------------------------------- I think I explained this badly. As we saw, if you casually encounter the words Achsenspiegelung and Geradenspiegelung and they are new to you, it may not be clear that they refer to the same thing. With any reasonable English translation of the two words, the sameness would be obvious and not worth mentioning. I would call them both "reflection," if necessary "reflection across a line (in a plane)," and Punktspiegelung as "point reflection" or one of its synonyms. https://www.mathsisfun.com/geometry/reflection.html https://en.wikipedia.org/wiki/Reflection_(mathematics) https://en.wikipedia.org/wiki/Point_reflection |
