Properties of Prisms

  • The bases of a prism are congruent polygons, and are parallel.
  • The Lateral faces are non-parallel sides which connects the 2 bases.
  • The edges of a prism are parallel.
  • The faces of a prism are polygons.
  • The volume of a prism is equal to the area of the base times the height.
  • The surface area of a prism is equal to the sum of the areas of the bases and the areas of the sides.

Prisms are used in a variety of applications, including:

  • Optics: Prisms are used to bend light, and they are used in a variety of optical devices, such as telescopes, binoculars, and microscopes.
  • Architecture: Prisms are used to create beautiful and interesting architectural features, such as skylights and windows.
