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 ShapesTwo-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.
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.
