![]() ![]() The lateral surface area (LSA) of a triangular prism is the sum of the surface area of all its faces except the bases. It is expressed in square units such as m 2, cm 2, mm 2, and in 2. The surface area of a triangular prism is the entire space occupied by its outermost layer (or faces). Like all other polyhedrons, we can calculate the surface area and volume of a triangular prism. So, every lateral face is parallelogram-shaped. Oblique Triangular Prism – Its lateral faces are not perpendicular to its bases.Right Triangular Prism – It has all the lateral faces perpendicular to the bases.Find the surface area of this right triangular prism. It is expressed in square units such as \(\textrm h)L\) = \((Length \times Perimeter)\).ġ. Let us learn about them in detail along with the formula. ![]() There are two important formulae of a triangular prism which are surface area and volume of triangular prism. The figure given below shows the net of a triangular prism where the triangles and the rectangles can be seen. It shows that the bases of the prism are shaped in a triangle and the lateral faces are shaped like a rectangle. This net can be folded up to make a triangular prism. The net of a triangular prism is a pattern that is seen when the surface of the prism is opened, flattened, and laid out such that all the faces are seen clearly. Learn about the faces, edges, and vertices for different shapes. ![]() Its edges include 6 edges of two triangular bases (3 3) and 3 sides that join the bases. The vertices of the triangular prism are the vertices of the two triangular bases connected by lines that form rectangles. So, every lateral face is parallelogram-shaped.Ī triangular prism has 5 faces including 3 lateral rectangular faces and 2 triangular bases, 9 edges, and 6 vertices. Oblique Triangular Prism: An oblique triangular prism has its lateral faces not perpendicular to its bases. ![]() Other properties of triangular prisms remain the same. Right Triangular Prism: A right triangular prism is a prism in which the angle formed between the edges of triangular bases and edges of the rectangular faces is 90 degrees.Irregular Triangular Prism: An irregular triangular prism has its 2 bases that are not equilateral triangles.Regular Triangular Prism: A regular triangular prism is a triangular prism whose bases have regular triangles (all sides of which are equal, the angles between the base’s sides are 60 degrees), and the side faces are rectangles.It can also be a right or oblique triangular prism, depending on the alignment of its bases. Other real-life examples of triangular prisms are camping tents or chocolate candy bars.Ī triangular prism can be a regular or irregular triangular prism based on the uniformity of its cross-section. A triangular prism has 5 faces (3 rectangular lateral faces and 2 triangular bases), 9 edges, and 6 vertices.Ī common example of triangular prisms is prisms used in the physics lab for refracting white light. What is a Triangular Prism?Ī triangular prism is a three dimensional solid consisting of two identical triangular bases joined together by three rectangular faces. In this mathematics article, we will learn about triangular prisms, triangular prism faces edges vertices, triangular prism net, formulas for the volume of a triangular prism, how to draw a triangular prism, properties of triangular prism, and solve problems based on the triangular prism. ![]()
