Drawing a Triangular Prism

To draw a triangular prism, we start by drawing a triangle and then extend lines perpendicular to the base of the triangle to form the sides of the prism. Here's a simple representation of a triangular prism:

      /\
     /  \
    /____\
    |    |
    |    |
    |____|

Characteristics of a Triangular Prism

A triangular prism has the following characteristics: - Vertices: A triangular prism has 6 vertices. - Edges: It has 9 edges. - Faces: There are 5 faces in a triangular prism.

Visibility of Faces, Edges, and Vertices

In a drawing of a triangular prism, 3 faces, 6 edges, and 4 vertices are visible. The remaining faces, edges, and vertices are not visible in the drawing.
