a two-dimensional pattern that can be folded into a three-dimensional polyhedron

A figure made up of a large number of straight lines or curves, which are connected at certain points and related to each other by some specified law.

a 2-dimensional representation or model of a 3-dimensional figure or solid which may be obtained by unfolding the figure to show all of its faces

A plane polygon with diagonals which can be folded up into a polyhedron, sometimes in more than one way.

Adjacent Polygons Foldable to Create a Specific Polyhedron

a 2D shape that can be folded to give a 3D form, sometimes called a development

a two-dimensional pattern that can be folded into a three-dimensional shape

Often referred to in elementary school math. A flattened 3-D shape that can be turned into a 3-D object with glue/tape and folding.

a drawing of a polyhedron unfolded along its edges, to lay flat in a plane. The earliest known examples of nets to represent polyhedra are by Albrecht Durer.

A flat diagram consisting of plane faces arranged so that it may be folded to form a solid.

A plane figure obtained by opening and flattening a 3-D object.

A two-dimensional shape that can be folded into a three-dimensional figure is a net of that figure.

In geometry the net of a polyhedron is an arrangement of edge-joined polygons in the plane which can be folded to become the faces of the polyhedron. Polyhedral nets are a useful aid to the study of polyhedra and solid geometry in general, as they allow for models of polyhedra to be constructed from material such as thin cardboard.
