Adding depth makes a 3D object from a 2D shape.

Irregular 3-dimensional shapes.
All of the polygons because they don't have depth
In geometry three-dimensional shapes are solid figures or objects or shapes that have three dimensions length, width, and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height.
The Earth is NOT a geometric shape because the Earth is not bounded; meaning it does not have sides or measurable depth, height, or width.
Geometric lines have length and depth that can be endless. A line is typically used when computing linear geometry equations.
Shapes that have length, width and depth are considered to be 3 dimensional
They have length, width and depth
Height, width, and depth.
They have one fewer dimension; they lack depth.
2d shapes are circles, ellipses, polygons (triangles, quadrilaterals, pentagons, etc.), angles, other non polygon shapes (like when you draw a star and the lines cross over each other. 3d shapes are shapes with added depth, such as tetrahedron, pyramid, prism (such as a cube), sphere (a ball), cone, etc.
2d shapes only have length and width, while 3d shapes have length, width and depth.
