Is there a name for a closed-loop polygon (2D, such as a circle, square, triangle, etc.) which is "draped" over a cylinder (3D)?
Picture Dali's famous painting, The Persistence of Memory. If those clocks were of zero thickness, just circles melted over some 3D object, can you still call them polygons? They wouldn't be quadrilaterals, because they themselves do not have a third dimension.
Thank you for your insight!
