Regular triangular prism
A triangular prism is a polyhedron, the two faces of which are equal triangles lying in parallel planes, and the remaining faces (side faces) are parallelograms that have common sides with these triangles.
A regular triangular prism is a triangular prism whose bases have regular triangles (all sides of which are equal, the angles between the sides of the base are 60 degrees), and the side faces are rectangles.
The bases of the prism are regular triangles..
The side faces of the prism are rectangles.
The side edges of the prism are parallel and equal.
The dimensions of the prism can be expressed in terms of side length a and height h.
The total surface area of the prism is equal to the sum of the area of its lateral surface and the doubled area of the base.
The formula of the surface area of a triangular prism:
The volume of a prism is equal to the product of its height and the area of the base.
The formula of volume of a regular triangular prism:
The regular triangular prism can be inscribed into the cylinder.
The formula for the radius of the cylinder:
Historically, the concept of "prism" arose from Latin and meant - something sawed.
The animation demonstrates how two parallel planes cutting off the excess from the two bases of the prism. From a single workpiece, you can get both the regular prism and an oblique prism.
