The edges of a triangular prism are the line segments where two faces of the prism meet. Each triangular prism will have 9 edges in total - 3 along the base and 6 connecting the sides of the base to the top face.
show me a picture pointing where the edge is
I'm sorry, but I am unable to display pictures. However, you can search for a visual representation of a triangular prism online to see where the edges are located. The edges are the line segments that connect the vertices of the triangular faces of the prism.
