Faces of the triangular prism: The face of a solid is a plane or flat suface which joins with other faces to build the solid shape. Remember that the faces of all solids are two dimensional. There are 5 faces of a triangular prism. Look at the figure below showing all the five faces of a triangular prism one by one;

Base Face

Left Triangular Face

Front Rectangular Face

Right Triangular Face

Rear Rectangular Face

Please note that these five faces can be at different locations depending upon the shape of the prism and on which face prism is landing.

Edges:

An edge is the meeting line of two faces. There are 9 edges of a triangular prism. Look at the image below to understand and learn more about the edges of the three dimensional shapes:

Look at the prism ABCDEF at right; below are the names of 9 of its edges:

Line joining A and B is an Edge AB,

Line joining B and E is the Edge BF

Similarly BC, CD, DE, EA, AF, FC and FD are the rest of the 7 edges of the given prism.

Vertex of the Triangular Prism:

A vertex is a point where two or more edges meet. All the triangular prisms have 6 vertices and each of them is explained at the bottom of this page. Please note that a vertex is a point or the corner of the prism.
