No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
A right angle triangle is a plane figure not a 3d one.
Use the coordinates of the vertices.
The cross section, of a 3D object, is the 2D shape made when a 2D plane cuts across the 3D object. Often "cross section" refers to the shape made when the plane is at right angles to an axis of the 3D object but this need not be the case.
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.
Plane is the area provided to us for drawing in autoCAD. It may be of 2 types 2D plane or 3D plane, while viewing a 2D plane we can only see a 2D view of our drawing and on a 3D plane a 3D model created in autoCAD can be viewed.

3D projection is any method of mapping three-dimensional points to a two-dimensional plane. It is used for certain types of engineering drawings.
A 3D figure can be drawn on a flat plane (piece of paper) by using perspective.A horizon (horizontal) line is drawn across the page and a spot marked along the horizon. All side lines of the 3D shape must meet at the spot.Perspective is much used by artists and architects, etc.

3D shapes don't have lines of symmetry they have plane's of symmetry.
they just want to get a 3d image of a place. they can also experiment on a model a plane modey making rust on a plane (pooring fluids on it haha)
