A geometric net is a 2-dimensional shape that folds into a 3-dimensional shape, usually a polyhedron. Each side of the polyhedron is a polygon. The simplest nets have four sides and are called tetrahedra.
There can be multiple nets that fold into the same 3-dimensional figure. Here
are a few examples of nets of cubes:
Not every 2-dimensional figure of polygons can be folded into a 3-dimensional shape.
Here are some figures with six squares that are not nets of cubes:
