I hope that is not a stupid question.
I met some sections, someone gave me the definitions to determine the exact name.
I want to know the community, if a section in particular may continue to be called lenticular and if the definitions I gave are correct.
Maybe it's a subtlety, but for me it's important to know.
I attach some photos, explaining the total number of edges or corners. I have omitted, for simplification, the fuller, as it can be disturbing for what I want to clarify here.
Any thoughts would be appreciated

???? section with two equal arcs, two different arcs as a link to the cutting line, total 4 arcs. Is correct to call this section lenticular?
