Triangular Prism

What is a Triangular Prism?

A triangular prism is a 3D geometric shape that consists of two triangular bases and three rectangular sides connecting to the corresponding vertices of the triangles. It has a total of five faces, nine edges, and six vertices.

What is the Volume of a Triangular Prism?

The volume (V) of a triangular prism is calculated using the formula:

V= 1/2 × base edge × height of the triangle × length of the prism

What is the Surface Area of a Triangular Prism?

The surface area (A) of a triangular prism involves finding the areas of the two triangular bases and three rectangular sides, then adding them:

A= 2 × area of base triangle + perimeter of base × height of prism

How many vertex does a Triangular Prism have?

A triangular prism has six vertices (corner points).

What is a Right Triangular Prism?

A right triangular prism is a specific type of triangular prism where the triangular bases are right-angled triangles, meaning one of the angles is 90 degrees.

What is the Difference between a Triangular Prism and a Rectangular Prism?

The key difference lies in the shape of their bases. A triangular prism has triangular bases, while a rectangular prism has rectangular bases. Triangular prisms have fewer edges and vertices compared to rectangular prisms with the same number of faces.

How many Edge does a Triangular Prism have?

A triangular prism has nine edges (line segments where the faces meet).

How many Face does a Triangular Prism have?

A triangular prism has five faces.

How to find the Area of a Triangular Prism?

We can find the area of a triangular prism using formula:

Total Surface Area (TSA) = (b × h) + (s1 + s2 + s3) L



Triangular Prism

Triangular Prism is a three-dimensional geometric shape with two identical triangular faces connected by three rectangular faces. It is one of the classifications of prism. It is named a triangular prism because it has a triangle across its cross-section.

This article covers the meaning of prism and triangular prism, the properties of the prism, the formula of a triangular prism, and the net of a triangular prism. We will also see the types of triangular prism on the basis of uniformity and alignment and verify Euler’s rule for triangular prism.
