A projection is a 2 dimensional representation of a solid figure. See related link.
Plane figure
a solid
A two-dimensional representation of a solid figure is known as a net. It shows all the faces of the three-dimensional shape unfolded into a flat surface, allowing you to see how the shape is constructed and visualize its different parts. Nets are helpful for understanding the properties and structure of 3D shapes.
A pattern that you can cut and fold to make a model of a solid shape.
A photograph is a two dimensional representation of a real-life scene. A hologram is three a dimensional representation.
A map, painting, or photograph, are all two dimensional representatins of three dimensional objects
a geographical map
the difference between a two dimensional shape and and a solid is that a two dimensional shape is plane and a solid you can see the whole shape a the inside.
