La géométrie aide à viser le bon angle.

Questions & Answers about La géométrie aide à viser le bon angle.

Why is it aide à viser and not just aide viser?
The verb aider (to help) requires the preposition à when it is followed by an infinitive verb. You will often see this structure as aider à faire quelque chose (to help to do something).
In English we say "aim at," so why isn't there a preposition after viser?
In French, viser is a direct transitive verb when talking about aiming or targeting something. This means it connects directly to its object without a preposition. You just say viser le bon angle, which covers both "aim" and "at."
I learned that "right angle" in math is angle droit. Why does this sentence use le bon angle?
Here, bon means "right" in the sense of "correct." The sentence means geometry helps you aim at the correct angle for your shot or calculation. If it meant a literal 90-degree geometric angle, it would indeed be l'angle droit.
Why is there a La before géométrie?
In French, general categories, abstract concepts, and academic subjects require a definite article. Because géométrie is a feminine noun, it uses La, even though English leaves "Geometry" article-free.
