Prisms and Pyramids
What is a Prism?
A prism is a 3 dimensional shape, having 2 identical ends and having the same cross section along its length.
All the faces of the prism are flat faces.
The 2 identical bases of the prism can be any polygon shape. All
other faces of a prism are parallelograms or rectangles. Different
types of pyramids are classified based on different types of shapes of
the 2 identical bases.
What is a Pyramid?
A pyramid is a 3 dimensional shape, with a single polygon shape base, and flat triangular sides, that meet at the common top point called the apex.
The base of the pyramid can be any polygon shape. All other
faces of a pyramid are triangular.
All the faces of the pyramids are flat faces.
There are several types of Prisms and Pyramids.
For example a pyramid with a hexagonal base is known as
hexagonal pyramid and a prism with hexagonal bases is known
as hexagonal prism.
Similarly a pyramid with a pentagonal base is known as
pentagonal pyramid and a prism with pentagonal bases is
known as pentagonal prism.
The video above describes prisms and pyramids and shows
images of hexagonal prism and hexagonal pyramid.
