Triangular Prism Basics


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;

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.
