Shapes can be classified as either two-dimensional or three-dimensional. Two-dimensional shapes are flat and defined by lines, while three-dimensional shapes enclose volume. Common two-dimensional shapes include circles, triangles, and squares. Three-dimensional shapes have length, breadth, and height and properties like faces, vertices, and edges. Real-world objects can also contain a mixture of different shapes.

3. What Are Shapes?
A shape is a geometrical figure that can
be described with mathematics. One
way to classify shapes is to describe a
bigger shape that the shape fits inside of.
For example, two-dimensional shapes
like circles will fit inside of a flat plane.
Three-dimensional objects like cubes will
not fit inside of a plane, because they
are not flat.
4. 2-dimensional Shapes
These are two-dimensional shapes or flat
plane geometry shapes. Their sides are made of
straight or curved lines. They can have any
number of sides. Plane figures made of lines are
called polygons. Triangles and squares are
examples of polygons
5. Properties Of 2
Dimensional Shapes
Two-dimensional shapes are planar. Graphically speaking, they
depend on only two coordinates--x and y, for instance--
consisting of x units and y units, respectively. In the case of a
coordinate system of more than two dimensions, then a 2-D
shape would still depend on two coordinate directions. For
example, in a spatial xyz coordinate system (which is three-
dimensional) a two-dimensional shape would be expressed with
points such as (x,y,0), (x,0,z), or (0,y,z). Therefore, it would
depend on either x and y, x and z, or y and z.
2-D shapes include the square, the triangle, the rhombus, etc.
To understand it more easily, you can say that 2-D shapes do
not have prominent or rugged parts. For example, speaking
two-dimensionally you would have a square, whereas three-
dimensionally you would have a cube, which is like an extended
or prominent square.
6. 3-Dimensional
Shapes
A 3D shape is a solid which
encloses a volume and has
length, breadth and height
7. Properties Of 3
Dimensional Shapes
Three-dimensional shapes have four
properties that set them apart from two-
dimensional shapes: faces, vertices, edges
and volume. These properties not only
allow you to determine whether the
shape is two- or three-dimensional, but
also which three-dimensional shape it is.
