 French term or phrase: angle creux This term is used to describe a signaling device for signs along roads, railroad tracks, etc. It says, "deux faces contigües de l'élément prismatique forment un angle creux." I understand the idea, but am not sure how to say it in English - the two faces form an angle of less than 180 degrees. Can you say "an inverted angle"?

Explanation:
For pointing, it would surely be less than 90 degrees, no?

obtuse angle

Explanation:
It seems to me this would be the general term for your shallow angle of less than 180° --- in the prismatic context, definitely NOT acute, I'd have thought

Mind you, maybe 'shallow angle' itself is actually what is needed! I'm thinking of the idea of two adjacent facets of a primsatic element

Good luck!

shallow angle

Explanation:
This is the first term that came to mind when I saw your query. And then when I had read the other suggestions, I was even more sure that it was what was needed. So I agree with Dusty.
