Did you know?
- The word រ៉ាប៉េទ័រ is a phonetic adaptation of the French 'rapporteur'. In French, 'rapporteur' can mean a protractor, but it also means a person who reports or presents a committee's findings.
- While រ៉ាប៉េទ័រ is used in schools, Khmer speakers often use the phrase បន្ទាត់វាស់មុំ, which literally translates to 'angle measuring ruler'.
- In Khmer, the word for 'ruler' បន្ទាត់ is the root for many measuring tools, but រ៉ាប៉េទ័រ is one of the few that ignores this root entirely in favor of a foreign loan.
