Questions & Answers about Le professeur explique les angles du triangle.
If the teacher is a woman, can I say la professeure instead of le professeur?
Yes. Historically, professeur was always masculine regardless of the teacher's gender. Today, the feminized form la professeure is widely used and officially accepted in everyday French. In informal speech, you will also hear la prof.
Why isn't there a preposition after explique?
The verb expliquer (to explain) takes a direct object for the thing being explained, meaning it connects directly to les angles without a preposition. However, if you want to mention who is receiving the explanation, you must use the preposition à. For example: Il explique les angles aux élèves (He explains the angles to the students).
Is there a liaison between les and angles?
Could I use the word enseignant instead of professeur here?
Enseignant is a broad term for anyone whose profession is teaching (an educator). Professeur is more specific and typically refers to a teacher at the middle school, high school, or university level. Both are correct, but professeur is more common when referring to a specific person teaching a specific subject in a classroom.
