3D Scan - Dodecahedron
A 3D scan is taken of a dodecahedron.
To do this a plane starts at one face and is slowly lowered until it gets to the opposite face always staying parallel to, and between, those two faces.
The picture above shows it when this process is half way completed.
As it is lowered, the cross section takes on a variety of polygons with different numbers of edges.
Which of the following shows this progression, i.e. the number of edges the cross section has, as it is lowered?
