Bases of the Right Triangular Prism

Bases of the right triangular prism

The bases of a triangular prism or right triangular prism are actually two triangles that we can find on each side of the prism.

These two triangles are always equal. Moreover, they can be any type of triangle. Let's review the types of triangles we know:

We use the bases of the prism to calculate the volume, the lateral surface area, and the surface area of the prism.

From the above examples we can see that triangular prisms have five faces, two of them are called the bases of the prism, and the remaining three are the lateral faces.

We can classify the prism by the number of sides its base has. For example, if the base has three sides we will have a triangular prism, if the polygon has four sides we can have a quadrangular or rectangular prism.

Here are some examples of right triangular prisms. The painted parts are the bases of the prism:

Questions on the bases of the right triangular prism

Which polygon forms the base of a triangular prism?

In a triangular prism, the base polygon is a triangle.


What are the parts of a triangular prism?

A triangular prism is formed by two equal and parallel triangles, called bases, and three rectangles called lateral faces.


How do you calculate the volume of a triangular prism?

First we must calculate the area of the base, in this case using the formula to obtain the area of a triangle "base times height over two". The result obtained is multiplied by the height of the prism and thus we obtain the volume of the triangular prism base.
