Triangular Prism. In geometry, a right triangular prism is a three-sided prism. A polyhedron with two congruent and parallel faces and whose lateral faces are parallelograms. The shape of the base gives the prism its name.That is, a prism with triangular bases is a triangular prism.riangular Prism. In geometry, a right triangular prism is a three-sided prism.

The simple definition of a prism is a solid object that has the same cross-section along the entire length of its shape. When you cut straight across an object, the cut portion is called a cross-section. Draw any shape using straight lines. Now use your imagination to see it extend upward and that is a prism. In eyeglasses, prisms are used primarily for double vision, positional correction, or convergence correction. Double vision (diplopia) is when a viewer sees two individual images using both eyes, instead of the one most people see, merged together by the brain.
